For the reaction \[2HI\]⇌\[{{H}_{2}}+{{I}_{2}}\], the rate of the reaction is proportional to \[{{[HI]}^{2}}\]. This means that the reaction is [AMU 1985; MP PET 2000]
A) Unimolecular
B) Bimolecular
C) Of first order
D) Of second order
Correct Answer:
D
Solution :
\[\frac{dx}{dt}={{(HI)}^{2}}\], then order of reaction = 2
