Question
CO(g) + 2 H2(g) ⇄ CH3OH(g) DH < 0
The synthesis of CH3OH(g) from CO(g) and H2(g) is represented by the equation above. The value of Kc for the reaction at 483 K is 14.5.
A 1.0 mol sample of CO(g) and a 1.0 mol sample of H2(g) are pumped into a rigid, previously evacuated 2.0 L reaction vessel at 483 K. Which of the following is true at equilibrium?
A.
[H2] = 2[CO]
B.✓ Correct
[H2] < [CO]
C.
[CO] = [CH3OH] < [H2]
D.
[CO] = [CH3OH] = [H2]
