The decomposition reaction of ammonia gas on platinum surface has a rate constant R = 2.5 x 10^-4mol L^-1. What is the order of the reaction.

For the reaction Cl_{2 (g)} + 2NO _(g) ⟶ 2NOCI_(g)
The rate law is expressed as rate = K[Cl₂] [NO]²
What is the overall order of this reaction?

Write the units of zeroth, first, second and third order rate constants.

If the rate of a reaction gets doubled as the temperature is increased from 27^oC to 37^oC. Find the activation energy of reaction?

Mention the factors that affected the rate of a chemical reaction.
