Question

The rate of the reaction $\mathrm{A}+2 \mathrm{~B} ightarrow 3 \mathrm{C}$ increases 72 times, when concentration of A is tripled and that of $B$ is doubled. The order of this reaction with respect to $A$ and $B$ are...... and........respectively\

Professor PC Thomas Classes · Answer

Rate $=k[A]^{2}[B]^{3}$ i.e. $3^{2} 	imes 2^{3}=9 	imes 8=72$\
