(a)
Interpretation:
The effect of decrease in pressure on the yield of the product has to be predicted.
Concept Introduction:
Le Chatelier principle states that, whenever a change in temperature, pressure or volume is experienced by a system at equilibrium, the system will undergo reactions to cancel that effect and reattain equilibrium.
Changes in pressure have significant effect on the reactions containing gas molecules. When pressure is increased, the system will try to decrease the pressure by reducing the number of gas molecule. That is, the reaction will occur to the direction where the number moles of gases are low. When the pressure is decreased, the reaction will favor in the direction where the number moles of gases are high, so as to increase the pressure.
