Chemistry - Chemical Equilibrium Question with Solution | TestHub

A catalyst does not change the equilibrium constant, K, so statement (a) is incorrect. K depends only on temperature, not on initial concentrations, making statement (b) correct.

Equilibrium is a dynamic state where the forward and reverse reaction rates are equal, so statement (c) is correct.

The equilibrium constant, K, does not depend on the total pressure, so statement (d) is incorrect.

Therefore, the correct options are (b) and (c).
