Question

Pure gas –A was taken in a closed container at an initial pressure of 5atm the pressure in the container changed due to the reactions

$\underset{(g)}{A} ⇌ \underset{(g)}{B} + 2 \underset{(g)}{C}$

$\underset{(g)}{C} ⇌ \underset{(g)}{B} + \underset{(g)}{D}$

If the total pressure due to the mixture of gases A, B,C and D was found to be 10atm at equilibrium in which pressure due to C was 3 atm then kp for the first equilibrium is
