We’re being asked to determine the correct value of Kp at 0°C.
CO (g) + 2 H2 (g) ⇌ CH3OH (l) Kp = 2.25 x 104 at 298 K and ΔHrxn = -128 kJ/mol.
We can use the van't Hoff equation to solve for the Kp of the reaction at 0°C.
K1 = equilibrium constant at T1
K2 = equilibrium constant at T2
ΔHrxn = heat of vaporization (in J/mol)
R = gas constant (8.314 J/mol•K)
T1 and T2 = temperature (in K)
For the following reaction, Kp = 2.25 x 104 at 298 K and ΔHrxn = -128 kJ/mol.
CO (g) + 2 H2 (g) ⇌ CH3OH (l)
Which of the following is the correct value of Kp at 0°C?
A. 1.9 x 102
B. 2.5 x 106
C. 1.1 x 102
D. 2.5 x 103
E. 1.9 x 104
