Question

1. The following concentrations were measured for an equilibrium mixture at 500.K:

Concentration of N_2(g) = 0.041 M

Concentration of H_2(g) = 0.082 M

Concentration of NH_3(g) = 0.051 M

The balanced reaction is as follows:

N_2(g) + 3 H_2(g) ⇌ 2 NH_3(g)

Calculate the equilibrium constant, Kc, at 500.K for the reaction.

watch for sig figs please.

2. Methane (CH₄) reacts with hydrogen sulfide to yield H₂ and carbon disulfide:

CH_4(g) + 2 H₂S_(g) ⇌ CS_2(g) + 4 H_2(g)

What is the value of Kp at 1000. K if the partial pressures in an equilibrium mixture at 1000. K are 0.21 atm of CH₄, 0.94 atm of H₂S, 0.23 atm of CS₂, and 0.97 atm of H₂?

watch for sig figs please.
