Problem: Given that Kp = 1.5 x 10-4 for the reaction 2 CO(g) <=> C(graphite) + CO2(g), what is the partial pressure of CO2(g) at equilibrium if initially 4.00 atm of CO(g) is in contact with graphite?a. 3.9952 atmb. 1670 atmc. 0.0083 atmd. 835 atme. 0.0024 atm

FREE Expert Solution

We’re being asked to calculate the partial pressure of CO2(g) at equilibrium if initially, 4.00 atm of CO(g) is in contact with graphite:

2 CO(g) C(graphite) + CO2(g);  Kp = 1.5 x 10-4


We're given the initial pressure of COs:

PCO = 4.00 atm

From this, we can construct an ICE table:


The Kp expression for the reaction is:
