FREE Expert Solution

When dealing with equilibrium:

Kc → equilibrium units are in molarity 
Kp → equilibrium units in terms of pressure


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


Calculate c:
