Give one example of the reaction where order and molecularity are the same.
Mention any two factors that influence the rate of chemical reaction.
If for the reaction A → products, a straight line graph passing through origin is obtained between the rate of reaction against concentration of A, what would be the order of reaction? Why?

उत्तर
- \[\ce{2NO_{2(g)} -> 2NO_{2(g)} + O_{2(g)}}\]
The order of a reaction is 2 and its molecularity is also 2. - Temperature, use of catalyst
- The reaction would be first order.
The differential rate law for the first-order reaction A → products is
The equation is of the form y = mx + c. A plot of rate versus [A]t is a straight line passing through the origin. The slope of straight line = k.
Variation of rate with [A]
