ethz.ch1 Chemical reactions 1.1 Rate of reaction and dependence on temperature We will once again look at the formation of ammonia (NH 3) from nitrogen and hydrogen (see section Chemical equilibrium of the thermodynamics chapter). This reaction follows the equation: N 2 + 3H 2 2NH 3 (1) H0 = 92 kJ mol S0 = 192 J mol K
