Solution

The correct option is D Assertion is incorrect but Reason is incorrect
Both Assertion and Reason are incorrect.
Consider an example of the reaction between nitrogen and hydrogen to form ammonia.
$N_{2} + 3 H_{2} ⇌ 2 N H_{3}$
The total pressure will be equal to the pressure exerted by the reacting gases nitrogen and hydrogen and the pressure exerted by ammonia.
The pressure of ammonia is not necessarily equal to the sum of the pressure of nitrogen and hydrogen.
