Consider the following reaction.
H2(g) + I2(g) 2 HI(g)
a. Write the expression for the equilibrium constant.
K =
b. Calculate K using the following concentrations of each substance at equilibrium:
[H2] = 8.6 M; [I2] = 0.087 M; [HI] = 0.27 M.
Use significant figures in reporting your answer.
K =
Explanation / Answer
a. K =[HI]2 / ( [H2] [I2])
b. K = [0.27]2 / [8.6] [0.087]
K = 0.09743384121
K = 0.097
