Vedclass · Accepted Answer

The equilibrium constant of a reaction changes with temperature.

Vedclass · Answer

(A) $1$. The equilibrium constant $(K)$ is a function of temperature only for a given reaction. It changes when the temperature changes.$2$. It is independent of the initial concentrations of the reactants or products.$3$. For the reaction $3Fe_{(s)} + 4H_2O_{(g)} \rightleftharpoons Fe_3O_{4_{(s)}} + 4H_{2_{(g)}}$,the equilibrium constant expression is $K_c = \frac{[H_2]^4}{[H_2O]^4}$. This reaction involves gases and solids. In an open vessel,the gaseous products escape,preventing equilibrium from being established. Therefore,the equilibrium constant is only defined for a closed system.$4$. If a reaction is multiplied by a factor $n$,the new equilibrium constant becomes $K^n$. Thus,if multiplied by $2$,it becomes $K^2$,not $2K$.

Which of the following statements is correct regarding the equilibrium constant $(K)$?
