Question

Consider this reaction and its rate law.
2A + 2b----- Products
rate= k[B]
What is the order with respect to A?
What is the order with respect to B?
What is the overall reaction order?

Answer 1

Answer: The power of concentration of B in the rate law is one. Thus, order of the reaction with respect to B is one. Thus, the overall reaction order is 2.

Explanation:

Answer 2

The order with respect to A is 2.

The order with respect to B is 2.

The overall order of the reaction is 1.

Order of a reaction

• The exponents in a rate law explains the impacts of the concentration of the reactants on the reaction rate also it defines the order of the reaction.
• Here rate = k[B]
• Here the rate depends on the concentration of the reactant B and so the order of the reaction is 1.
• $2A + 2b --- > Products$
• The order of the reaction with respect to A is 2.
• The order of the reaction with respect to B is 2.
