To calculate the Kp of the reaction equation, we’re going to use Hess’s Law. We’re going to manipulate the two reactions with given Kp values such that when we add them together, we will get the reaction equation with the unknown Kc.
Unknown Kc value: A(g) ⇌ 2B(g) +C(g) Kc = ?
Reaction 1: A(g) ⇌ 2X(g) + C(g) Kc = 1.55
Reaction 2: B(g) ⇌ X(g) Kc = 25.2
Use the data below to find the equilibrium constant Kc for the reaction A(g) ⇌ 2B(g)+C(g)
A(g) ⇌ 2X(g) + C(g) Kc=1.55
B(g) ⇌ X(g) Kc=25.2
