SandraSue's comment:
"Excellent. Thanks."
Response Details:
Write the equilibrium constant expression, Kp, for the reaction and the answer just pops right out at you!
 
Kp = PCO2
That being the case, the pressure must be 1.20 atm.
Spending precious time on a problem that results in a rating of "not helpful" or "somewhat helpful" is deemed a wasted effort. With certainty, I'll be sure not to provide assistance in that direction again.
