AP Chemistry Equilibrium Worksheet apchemequiws0809.doc Name: _______________________________ Date: ____________ Period: _____ 1. Carbon monoxide and hydrogen react according to the following equation: CO (g) + 3H 2(g) CH 4(g) + H 2 O (g) When 1.000mol CO and 3.000mol H 2 are placed in a 10.00L vessel at 927 o C (1200.K) and allowed to come to equilibrium, the mixture is found to contain 0.387mol H 2 O. What is the molar composition of the equilibrium mixture? That is, how many moles of each substance are present? 2. a. Write the equilibrium constant expression K c for catalytic methanation. CO (g) + 3H 2(g) CH 4(g) + H 2 O (g) b. Write the equilibrium constant expression K c for the reverse of the previous reaction CH 4(g) + H 2 O (g) CO (g) + H 2 O (g) c. Write the equilibrium constant expression K c for the synthesis of ammonia. N 2(g) + 3H 2(g) 2NH 3(g) d. Write the equilibrium expression K c when the equation for the previous reaction is written ½ N 2(g) + 3/2 H 2(g)
