Answer 4.1

Chemical Equilibria|Le Chatelier's Principle|Factors Affecting Chemical equilibria| The Haber Process|The Contact Process|Equilibrium Constants Write expressions for Kc for each of the following:
 * 1) N2(g) + 3H2(g) <=> 2NH3(g)
 * 2) I2(s) <=> I2(g)
 * 3) I2(g) + H2(g) <=> 2HI(g)
 * 4) N2O4(g)<=> 2NO2(g)

Answer: 2   1   3            1. Kc = [NH3]/[N2][H2]

2. Kc = [I2]

3. Kc = [HI] /[I2][H2]

2           4. Kc = [NO2]/[N2O4]
