A(aq) + B (s) =C(aq) + D(aq) H<0

Indicate whether the concentration of reactant A will increase,decrease or remain the same .

1 If a catalyst is added
2 some C is removed from the system
3 some D is added to the system
4 the system is cooled
5 some B is added to the system

Consider the following reversible reaction occurring in a 1.00 L enclosed vessel:
(NH4)2SO4(s) 2NH3(g) + H2SO4(g)
Given that the value of the equilibrium constant, Kc, of this reaction is 2.57 × 10-5, calculate the molar concentrations of NH3(g) and H2SO4(g) at equilibrium. No NH3(g) and H2SO4(g) were present initially.
