Consider the following system at equilibrium at 573 K: 2NO(g) +C1,0) = 2NOCID) + 18.4 kcal Indicate whether each individual change would favor the production of NOCI(g). Evaluate each change separately, assuming that all other conditions remam constant. Decreasing the temperature Decreasing the pressure. Increasing the volume. Adding NOCI Removing Cl. 21e

Answer 1

*** Le Chatelier's principle :- - According to this prineple in a system in equilibrium in subjected to a change of. temperature, pressure and concentration then the equilibrium Shifts in such a way that the I effect of the change applied on the reaction is nullified I According to this principle : 4. Increase in Tempshifted the equalibrium in the forward direction for endothermic neordion N2 (g) tos (g) + 43.2 kcal ² 2NOG) A BH = +43:2 kcal 2. Decrease in temperature shifty the equilibrium in the forward direction for exothermic reaction and vice-vewa N₂(g) + 3H₂(g) = 2NH₃ GF #23 kcal Du E - 23 Keel 3.
