The rate of a chemical reaction depends on the concentrations of the reactants. For the general reaction between A and B ,

aA+bB⇌cC+dD

The dependence of the reaction rate on the concentration of each reactant is given by the equation called the rate law:

rate=k[A]^m[B]^n

where k is a proportionality constant called the rate constant. The exponent m determines the reaction order with respect to A , and n determines the reaction order with respect to B . The overall reaction order equals the sum of the exponents (m+n ).

Part A

What is the reaction order with respect to A ?

Express your answer as an integer.

Part B

What is the reaction order with respect to B ?

Express your answer as an integer.

Part C

What is the reaction order with respect to C ?

Express your answer as an integer.
