1.
A student ran the following reaction in the laboratory at 425 K:
PCl5(g)
PCl3(g) + Cl2(g)
When she introduced 3.38 moles of PCl5(g) into a 1.00 liter container, she found the equilibrium concentration
of Cl2(g) to be 3.38×10-2 M.
Calculate the equilibrium constant, Kc, she obtained for this reaction.
2.
The equilibrium constant, Kc, for the following reaction is 10.5 at 350 K.
2CH2Cl2(g)
CH4(g) + CCl4(g)
Calculate the equilibrium concentrations of reactant and products when 0.306 moles of CH2Cl2 are introduced
into a 1.00 L vessel at 350 K.
