(A) The rate law is given as $r = k[C_2H_5I]^1$. The exponent of the concentration term in the rate law is $1$,so the order of the reaction is $1$. Since the reaction involves the decomposition of a single molecule of $C_2H_5I$ in the elementary step,the molecularity is $1$. Therefore,both the order and molecularity of this reaction are $1$.
