What is the Kp for this (all information is given?)?

Question

CO2(g) + H2(g) ↔ H2O(g) + CO(g)

When H2(g) is mixed with CO2(g) at 2,000 K, equilib­rium is achieved according to the equation above.

[CO] = 0.385 M
[H2O]= 0.385 M
[H2]= 0.365 M
[CO2] = 0.465 M
And if it helps Kc = 0.87

Answer 1

I'm not sure how to do it.
