The second-order rate law for the reaction A -> products is given by:
rate = k[A]^2
where k is the rate constant and [A] is the concentration of A.
We can use the integrated rate law for a second-order reaction to solve for the concentration of A at a given time t:
1/[A] - 1/[A]₀ = kt
where [A]₀ is the initial concentration of A.
We are given k = 0.540 M¯¹s¯¹ and we want to find the time at which [A] = 1/3[A]₀.
So, we can rearrange the integrated rate law equation to solve for t:
t = (1/[A] - 1/[A]₀) / k
Plugging in [A] = 1/3[A]₀ and simplifying:
t = (1/(1/3[A]₀) - 1/[A]₀) / k
t = (3/[A]₀ - 1/[A]₀) / k
t = 2/[A]₀k
Substituting the given values:
t = 2 / (0.540 M¯¹s¯¹ x [A]₀)
So, to find the time at which [A] = 1/3[A]₀, we need to know the initial concentration of A. If we assume an initial concentration of [A]₀ = 1.0 M, then:
t = 2 / (0.540 M¯¹s¯¹ x 1.0 M) = 3.7 s
Therefore, the concentration of A will be 1/3 of its original concentration after 3.7 seconds.

We can use the ideal gas law to determine the pressure of the gas:
PV = nRT
where P is the pressure, V is the volume, n is the number of moles, R is the gas constant (0.08206 L atm K¯¹mol¯¹), and T is the temperature in Kelvin.
First, we need to convert the temperature from Celsius to Kelvin:
T = 200°C + 273.15 = 473.15 K
Now we can plug in the values we have been given:
P(17.3 L) = (0.500 mol)(0.08206 L atm K¯¹mol¯¹)(473.15 K)
Solving for P:
P = (0.500 mol)(0.08206 L atm K¯¹mol¯¹)(473.15 K) / (17.3 L) = 6.05 atm
Therefore, the pressure of the gas in the container is 6.05 atm.

First, we need to convert the temperature from Celsius to Kelvin:
T = 20°C + 273.15 = 293.15 K
Now we can plug in the values we have been given:
P(17.3 L) = (0.500 mol)(0.08206 L atm K¯¹mol¯¹)(293.15 K)
Solving for P:
P = (0.500 mol)(0.08206 L atm K¯¹mol¯¹)(293.15 K) / (17.3 L) = 2.50 atm
Therefore, the pressure of the gas in the container is 2.50 atm.
To determine the limiting reactant and the maximum theoretical moles of the product, we need to compare the amount of each reactant to their stoichiometric ratios in the balanced chemical equation.
The balanced chemical equation for the reaction between aluminum and oxygen to form aluminum oxide is:
4Al + 3O2 → 2Al2O3
The molar mass of aluminum is 26.98 g/mol, and the molar mass of oxygen is 32.00 g/mol. Using these values, we can calculate the number of moles of each reactant:
Number of moles of Al = 2.82 g / 26.98 g/mol = 0.1046 mol
Number of moles of O2 = 2.56 g / 32.00 g/mol = 0.0800 mol
To determine the limiting reactant, we need to calculate the number of moles of product that each reactant can produce based on their stoichiometric ratios in the balanced equation. For aluminum, based on the balanced equation, 4 moles of aluminum react with 3 moles of oxygen to produce 2 moles of aluminum oxide. Therefore, the number of moles of aluminum oxide that can be produced from 0.1046 moles of aluminum is:
0.1046 mol Al x (2 mol Al2O3 / 4 mol Al) = 0.0523 mol Al2O3
For oxygen, based on the balanced equation, 3 moles of oxygen react with 4 moles of aluminum to produce 2 moles of aluminum oxide. Therefore, the number of moles of aluminum oxide that can be produced from 0.0800 moles of oxygen is:
0.0800 mol O2 x (2 mol Al2O3 / 3 mol O2) = 0.0533 mol Al2O3
So, we can see that oxygen is the limiting reactant because it can only produce 0.0533 mol of aluminum oxide, while aluminum can produce 0.0523 mol of aluminum oxide. Therefore, the maximum theoretical moles of aluminum oxide that can be produced is 0.0533 mol.
Note that we could have also determined the limiting reactant by comparing the mole ratio of the reactants to their stoichiometric ratios in the balanced equation. The mole ratio of aluminum to oxygen is:
0.1046 mol Al / 0.0800 mol O2 = 1.3075
The stoichiometric ratio of aluminum to oxygen in the balanced equation is:
4 mol Al / 3 mol O2 = 1.3333
Since the mole ratio is less than the stoichiometric ratio, oxygen is the limiting reactant.
Fe2+ is the ion formed when an iron atom loses two electrons. When Fe loses two electrons, the electronic configuration changes to 1s2 2s2 2P6 3s2 3s2 3p6 3d6.
In Fe2+, the ion has a +2 charge, which means it has lost two electrons. Therefore, the electronic configuration of Fe2+ is:
1s2 2s2 2P6 3s2 3s2 3p6 3d6
In this configuration, there are 6 d electrons present, because Fe2+ has lost the two outermost 4s electrons, but the d electrons remain unchanged. Therefore, there are 6 d electrons present in Fe2+.
To determine the direction of the reaction, we need to compare the current reaction quotient, Qc, with the equilibrium constant, Kc.
The reaction quotient is calculated using the concentrations of the reactants and products at any given time. For the given reaction:
Qc = [C]^1 / [A2]^1 ^2
Substituting the given concentrations:
Qc = (5.2) / (2.0)(0)^2 = infinity
Since Qc is greater than Kc, the reaction will shift to the left to reach equilibrium. This means that the concentration of A2 will decrease and the concentration of B will increase, while the concentration of C will decrease. The reaction will continue to shift to the left until Qc = Kc.
