At some temperature. Kc = 33 for the reactionH2(g) + I2(g) ⇄ 2 HI(g)Assume the initial concentrations of both H2 and I2 are 6.00 × 10−3 mol/L. Find the concentration of each reactant and product at equilibrium.

Interpretation Introduction

Interpretation: Equilibrium concentration of the reactant and product has to be identified.

Concept Introduction: At equilibrium the concentration of the reaction and the product is equated to a constant K, where K is known as the equilibrium

If a reaction is as aA+bBcC+dD ,

The equilibrium constant K=[C]c[D]d[A]a[B]b

Explanation

The equilibrium constant Kc=[HI]2[H2][I2]

 Equation H2 I2 2HI Initial concentration 6.00× 10-3M 6.00× 10-3M 0 Change concentration −x −x −2x Equilibrium concentration 6.00× 10-3M - x 6.00× 10-3M - x +2x

Substitute in Kc equation

33=(+2x)2(6
