Question

Calculate the value of the equilibrium constant (Kp) for the reaction displayed if the following equilibrium pressure data were measured at 25.00 °C: P(H2(g)) = 0.2282 atm, P(I2(g)) = 0.1646 atm, P(HI(g)) = 5.462 atm.

H2(g)+I2(g) = 2HI(g)

Answer 1

I don't know what your problem is. Just substitute into Kp expression and solve. Or post your work and I can see what is going on.
