Answer 2

Given:

During the reaction if concentration of two reactants get changed.

To find:

What happens to order or reaction ?

Solution:

Let us assume the following chemical reaction involving two reactants:

$\therefore \: A + B \longrightarrow \: AB$

From this equation, the rate law can be expressed as :

$\therefore \: R = k { \bigg(A \bigg)}^{x} { \bigg(B\bigg)}^{y}$

Here the order of the reaction is given as (x + y), and the value of x and y are totally experimental.

As per the question, the concentration of A and B are changed.

• In that case , the value of R will change, that means that the rate of the reaction is going to change.

• However , value of x and y will remain same because these are experimental values independent of the concentration of the reactants.

• So, (x + y) will remain same.

So, order of the reaction remains unchanged.
