Which postulate of kinetic theory can be used to justfy Dalton's law of partial pressures ?

Explanation

To justify Dalton's law of partial pressures using the postulates of the kinetic theory, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Dalton's Law of Partial Pressures**:
Dalton's law states that in a mixture of non-reacting gases, the total pressure exerted by the mixture is equal to the sum of the partial pressures of each individual gas. Mathematically, it can be expressed as:
\[
P_{total} = P_1 + P_2 + P_3 + ... + P_n
