Question

3) A reaction vessel at 27 ∘C contains a mixture of SO2(P= 3.10 atm ) and O2(P= 1.10 atm ). When a catalyst is added the reaction 2SO2(g)+O2(g)⇌2SO3(g) takes place. At equilibrium the total pressure is 3.95 atm . Find the value of Kc.

4) Consider the following reaction: NH4HS(s)⇌NH3(g)+H2S(g)
An equilibrium mixture of this reaction at a certain temperature was found to have [NH3]= 0.282 Mand [H2S]= 0.370 M . What is the value of the equilibrium constant (Kc) at this temperature? What is Δn for the following equation in relating Kc to Kp?

5) N2(g) + 3 F 2(g) ↔ 2 NF 3(g)
