Question

For a given reaction the equilibrium constant Kc = 129 at -10.5 oC then:

Select one:

a. Reactants are always favored

b. Products are always favored

c. The system always shifts to the right to reach equilibrium

d. The system always shifts to the left to reach equilibrium

e. The system is at equilibrium

The reaction 2NO(g) + Cl2(g) <--> 2 NOCl(g) has a Kc = 6.5x104. The reaction is exothermic at 300K.

If the container was compressed to half its volume:

Select one:

a. nothing would change

b. The number of moles of NOCl would go up

c. the equilibrium constant would go up

d. the number of moles of Cl2 would go up

e. the equilibrium constant would go down

1) d. The system always shifts to the left to reach equilibrium

2) b. The number of moles of NOCl would go up
