Applying Concepts

These questions test conceptual learning.

Two molecules of A react to form one molecule of B, as in the reaction

Three experiments are done at different temperatures and equilibrium concentrations are measured. For each experiment, calculate the equilibrium constant, K_c.

(a) [A] = 0.74 mol/L, [B] = 0.74 mol/L

(b) [A] = 2.0 mol/L, [B] = 2.0 mol/L

(c) [A] = 0.01 mol/L, [B] = 0.01 mol/L

What can you conclude about this statement: “If the concentrations of reactants and products are equal, then the equilibrium constant is always 1.0.”
