Partial Pressure Chemistry help.?

[Jack Bauer]

At some temperature, K = 26.1 for the following reaction:

H2(g) + CO2(g) <---> H2O(g) + CO(g)

The initial partial pressures of H2 and CO2 are each 2.10 atm.

What is the final pressure of CO?

PCO = atm

What is the final total pressure?

Ptotal = atm

here is what i did for the first part...what am i doing wrong?

(_____) H2(g) + CO2(g) <---> H2O(g) + CO(g)
Initial : 2.10____ 2.10 _____ 0 _____ 0
Change: -x _______-x _______+x____ +x
Equil. : 2.10-x ___2.10-x ____ x _____ x


K = Products/ Reactants

26.1 = (X^2) / ((2.10 - x)^2)

i got x = 2.61 for the first part, but that is wrong. i also got 1.76, is that the right one? or am i just completely lost

any help is much appreciated
