Consider the reactiona + b → productsfrom the following data obtained at a certain temperature, determine the order of the reaction. enter the order with respect to a, the order with respect to b, and the overall reaction order.[a] (m) [b] (m) rate (m/s)1.50 1.50 3.20 ×10−11.50 2.50 3.20 ×10−13.00 1.50 6.40 ×10−1

Order with respect to A is 1 , order with respect to B is 0 and total order is 1

Explanation:

Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.

k= rate constant

x = order with respect to A

y = order with respect to A

n = x+y = Total order

a) From trial 1:    (1)

From trial 2:    (2)

Dividing 2 by 1 :

therefore y=0

b) From trial 2:      (3)

From trial 3:   (4)

Dividing 4 by 3:

, x=1

Thus rate law is

Thus order with respect to A is 1 , order with respect to B is 0 and total order is 1+0=1.

1. they vary with a higher number because boiling is way hotter than melting

c, liquids evaporate, creating a gas
