What is the rate constant of a reaction if rate = 0.2 (mol/l)/s, [a] and [b] are each 3 m, m = 1, and n = 2?

Answer : The rate constant of a reaction is,

Solution :

The general rate law expression is,

where,

k = rate constant

[A] and [B] are the concentrations

m is the order of reactant A and n is the order of reactant B

Now put all the given values in the above rate law expression, we get the value for rate constant.

Therefore, the rate constant of a reaction is,

c is the answer because when something is left after something evaporates that shows the chemical change.
