Pick out the wrong statement.

A) The conversion for a gas phase reaction increases with decrease in pressure, if there is an increase in volume accompanying the reaction B) With increase in temperature, the equilibrium constant increases for an exothermic reaction C) The equilibrium constant of a reaction depends upon temperature only D) The conversion for a gas phase reaction increases with increase in pressure, if there is a decrease in volume accompanying the reaction

Answer & Solution

Correct Answer: Option B

According to Le Chatelier's principle increase in temperature for an exothermic reaction will favor backward reaction and hence the product concentrations decreases and an new equilibrium is reached for an particular decrease in temperature and therefore the equilibrium constant decreases not increases.
$${K_c} = \frac{{C * D}}{{A * B}}.$$
