Question

Among the following, the correct statement about the chemical equilibrium is :

• A. Equilibrium constant is independent of temperature.
• B. Equilibrium constant tells us how fast the reaction reaches equilibrium.
• C. At equilibrium, the forward and the backward reactions stop so that the concentrations of reactants and products are constant.
• D. Equilibrium constant is independent of whether you start the reaction with reactants or products.

Answer 1

Answer: (D)

$\bullet$ Equilibrium constant is dependent on temperature.
$\bullet$ Equilibrium constant do not tell us about the rate of reaction.
$\bullet$ At equilibrium, the forward and backward reactions do not stop but they have same rate
