Consider the following reaction:

co2(g) + c(graphite) ⇌ 2 co(g)

a reaction mixture initially contains 0.56 atm co2 and 0.32 atm co. determine the equilibrium pressure of co if kp for the reaction at this temperature is 2.25.
a) 0.83 atm
b) 0.31 atm
c) 0.26 atm
d) 0.58 atm
e) 0.42 atm

A) 0.83 atm

Explanation:

The given reaction is:

The equilibrium constant Kp is given as:

Initial [CO2] = 0.56 atm

Initial [CO] = 0.32 atm

Set-up ICE table

initial                          0.56                                              0.32

Change                      -x                                                   +2x

Eq                              0.56-x                                             0.32+2x
