At 700 K, equilibrium constant for the reaction H_(2) (g) + I_(2) (g)

1.	At 700 K, equilibrium constant for the reaction H_(2) (g) + I_(2) (g) hArr hArr 2 HI (g)" is "548 If 05 " mol " L ^(-1) of HI (g) is present at equilibrium at 700 K, what are the concentrations of H_(2) (g) and I_(2) (g)assuming that we initially started withHI(g) and allowed it to reach equilibrium at 700 K.
Answer» SOLUTION :` 2 HI(g) hArr H_(2) (g) + I_(2) (g), K= 1/548 ` At equilibrium , ` [HI] = 05 "mol" L^(-1) , [H_(2)] = [I_(2)] = x "mol" L^(-1):. K= (x xx x)/(05)^(2)=1/(548).` This gives ` x = 0068 , i.e., [H_(2)] = [I_(2) = 0068 "mol"L^(-1) .`
