The energy barrier for this reaction is quite low, 37 kJ mol-1. There are many schemes for the estimation of the barrier height, E. The simplest of these are based on empirical correlations. For details see Steinfeld et al., 1989, p. 231. 

The reverse reaction (BC + A — AB + C) follows the same reaction coordinate in the opposite direction. The barrier for the reverse reaction occurs at the same place. The barrier height in the reverse direction is related to the barrier height in the forward direction by
