Question 4 options:

It would shift to the right, favor the forward reaction and the rate of reaction would decrease.

It would shift to the left, favor the forward reaction and the rate of reaction would increase.

It would shift to the right, favor the forward reaction and the rate of reaction would increase.

It would shift to the left, favor the reverse reaction and the rate of reaction would decrease.
