Question

The equilibrium constant, K_c, for the following reaction is 83.3 at 500 K.

PCl₃(g) + Cl₂(g) = PCl₅(g)

Calculate the equilibrium concentrations of reactant and products when 0.249 moles of PCl₃ and 0.249 moles of Cl₂ are introduced into a 1.00 L vessel at 500 K.  

[PCl3]	=	M
[Cl2]	=	M
[PCl5]	=	M

The equilibrium constant, K_c, for the following reaction is 1.80×10^-2 at 698 K.

2HI(g) = H₂(g) + I₂(g)  

Calculate the equilibrium concentrations of reactant and products when 0.252 moles of HI are introduced into a 1.00 L vessel at 698 K.  

[HI]	=	M
[H2]	=	M
[I2]	=	M
