Answer:

ANSWER

Solution:- (D) (a+b)>(c+d),ΔH<0

aA+bB⇌cC+dD

When pressure is decreased, the equilibrium will shift in a direction in which there is an increase in the number of moles. Due to this, the pressure will increase and invalidate the decrease in pressure. When the temperature of an exothermic reaction is increased, the reaction will proceed in the backward direction so as to absorb heat and invalidate the effect of increasing temperature. This will decrease the value of the equilibrium constant K

C

, i.e., the equilibrium will shift to left. The equilibrium shifts in the backward direction by low pressure and high temperature. This indicates that the total no. of moles of reactant is greater than the total no. of moles of product, i.e.,

(a+b)>(c+d).

This indicates that the reaction is exothermic, i.e.,

ΔH<0
