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.
