6. For the following equilibrium reaction: 2 HI (g) H,(g)-12(s) Predict whether this reaction will move in the forward direction, reverse direction, or

Solution

For exothermic reaction on increasing temperature equilibrium constant will decreases hence reaction will shift left means reverse direction.

For decrease in volume reaction will shift in that direction that cause decrease in moles of gas i.e forward direction.

Adding H2 cause the reaction to shift in reverse direction.

Decrease in pressure or increase in volume have same effect i.e shift in reverse direction.

Adding I2 has no effect due to its solid phase.
