Answer:
The reaction quotient Q is 20.7
Explanation:
Step 1: Data given
Number of moles NO2 = 1.02 *10^-1 = 0.102 moles
Number of moles N2O4 = 8*10^-3 = 0.008 moles
Volume = 27.0 L
Step 2: The balanced equation
2 NO2(g) ↔ N2O4(g)
Step 3: Calculate concentrations
Concentration = moles / volume
[NO2] = moles NO2 / volume
[NO2] = 0.102 moles / 27.0 L
[NO2] = 0.00378 M
[N2O4] = moles N2O4 / volume
[N2O4] = 0.008 moles / 27.0L
[N2O4] = 2.96 *10^-4 M
Q = [N2O4] / [NO2]²
Q = (2.96 *10^-4) / (0.00378²)
Q = 20.7
The reaction quotient Q is 20.7
When Q<K, there are more reactants than products. As a result, some of the reactants will become products, causing the reaction to shift to the right.
