FREE Expert Solution

We're being asked to determine which of the following statements describe the state of equilibrium for the chemical system R(g) ⇌ P(g).

Let's analyze each of the given statement.


A. Kp = Kc

Kp and Kc are related to one another by the following equation below: 

Kp=KcRTn

R = gas constant = 0.08206 (Latm)/(molK)
T = temperature, K
Δn = moles of gas products – moles of gas reactants

From the reaction: R(g) ⇌ P(g)
