Answer 4.2

Chemical Equilibria|Le Chatelier's Principle|Factors Affecting Chemical equilibria| The Haber Process|The Contact Process|Equilibrium Constants Calculate units for the following reactions: N2(g) + 3H2(g) <=> 2NH3(g) 2        3                         Units = (mol/dm3) /(mol/dm3) x (mol/dm3) =

I2(s) <=> I2(g)

Units = mol/dm3

I2(g) + H2(g) <=> 2HI(g) 2                        Units = (mol/dm3) /(mol/dm3)x (mol/dm3) = No units

N2O4(g)<=> 2NO2(g) 2                        Units = (mol/dm3) /(mol/dm3) = mol/dm3
