Question

In a reaction at equilibrium, ${}^{\prime }{x}^{\prime }$ mole of the reactant, $A$ decompose to give 1 mole each of $B$ and $C$. The experimental studies suggest that the decomposition of $A$ at equilibrium is independent of initial concentration of $A$. ${}^{\prime }{x}^{\prime }$ is

Answer 1

In a reaction at equilibrium, ${}^{\prime }{x}^{\prime }$ mole of the reactant, $A$ decompose to give 1 mole each of $B$ and $C$. The experimental studies suggest that the decomposition of $A$ at equilibrium is independent of initial concentration of $A$. This suggests that the reaction is of zero order. ${}^{\prime }{x}^{\prime }$ is 2.

eg.

$2HI\stackrel{hv}{⟶}{H}_2+I_2$
