Question

1. For the exothermic reaction below, increasing the pressure would

N2(g)+3H2(g)⇄2NH3(g)
a. increase [H2]
b. increase [NH3]
c. increase [N2]*** Would it move to the side with fewer gas molecules?
d. have no effect

2. If K=100, then the value of K for the reverse reaction is
a. the same value
b. can only be determined by experimentation ****
c. the negative of the value for the forward reaction
d. 0.01

Answer 1

1. Yes, the reaction will move to the side with the fewer gas molecules but that isn't answer c. You have 4 mols gas on the left and 2 mols on the right so it will move to the right. The correct answer is b.
2. b is not correct. For the reverse reaction K is 1/100 = ?

Answer 2

2. is d

Answer 3

right. K rev = (1/Kfwd)
