Can you explain how you get the answer?

Which of the following reactions lies to the right, favoring the formation of products, and which lies to the left, favoring formation of reactants? Part A 2 NO(g) + O2(g) 2 NO2(g); Kp = 5.0 x 10^12 reaction lies to the right, favoring the formation of products to the left, favoring formation of reactants Part B 2 HBr(g) H2 (g) + Br2 (g); Kc = 5.8 x 10^-18 reaction lies to the right, favoring the formation of products to the left, favoring formation of reactants

Explanation / Answer

Part A:

2NO2 (g)+ O2(g)            2NO2(g) here Kp = 5 X 1012 here equilibrium shift to right, formation of product is favoured.

Part B:

2HBr (g)        2H2 (g)+Br2(g) here Kc = 5.8 X10-18 here equilibrium shift to left, formation of reactant is favoured.

Reason:

Large value for K indicates that equilibrium is attained only after the reactants have been largely converted into products. So formation of product is favoured here.

Whereas a small value of K-much less than 1-indicates the equilibrium is attained when only a small proportion of the reactants have been converted into products. So formation id reactant is favoured here.

Part A

2NO(g) + O2
