The following reaction is first order in H2 and second order in NO with a rate constant of #2.9 * 10^2 M^(-2)*s^(-1)# .

#2NO_(g) + H_(2(g)) rarr N_2O_((g)) + H_2O_((g))#

Calculate the instantaneous rate when the reactant concentration #[NO]=0.00200M# and #[H_2]=0.00400M# . What is the overall order of the reaction?

Order of reaction is 3 and instantaneous rate(

#### Explanation:

According to question,order with respect to hydrogen is 1 and order with respect to NO is 2.So, according to Rate law,

From above rate equation, it is clear that order of reaction is 3 .

Substituting
