# Kp and Kc equations

2CO(g)+O2(g)=2CO2(g)

If Kc is 2.24 e22 at 1273 degrees C

what is Kp

I know it must seem silly, but I still can't figure out how to set it up. Can you show me again?

Solution:

There are three moles of gas on the left and only two on the right. So, the change in the moles of gas is -1. That is, n = -1.

T is the temperature in Kelvin, which is 1273 + ...
