Question

(Please show method and all work in latex for readability. Test is tomorrow)

6. (10 pts) Consider the effect on the equilibrium of the exothermic reaction

Predict whether the mixture shifts in the forward direction, the reverse direction, or no

change takes place when :

(a) The volume of the system is compressed ______________________

(b) The temperature of the system is decreased _______________________

(c) A catalyst is added to the system _______________________

_______________________

(e) NO is added to the system _______________________

Explanation / Answer

(a) When the volume of the system is compressed, equilibrium shifts in forard direction where there will be fewer no of moles of species.

(b) When the temperature of the system is decreased, equilibrium shifts in forard direction where heat is produced (exothermic reaction)

(c) When the catalyst is added to the system, equilibrium is unaffected.

(d) When the N2 product is removed from the system, equilibrium shifts in forard direction where more N2 is produced.

(e) When the NO reactant is added to the system, equilibrium shifts in forard direction where more NO is consumed.
