FREE Expert Solution

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 K­c:

Given:                        Kp = 6.7298

                                    T = 298 K
