Specification 4.6.2.1, 4.6.2.3 · Paper 2
Revise: Reversible ReactionsThis is the forward reaction as the equation is written. In a cooler part of the apparatus, the two gases react together and reform solid ammonium chloride: the reverse reaction.
The reaction in which reactants form products as the equation is written from left to right.
Specification 4.13, 4.14 · Paper 1
The reaction that proceeds from the substances written on the left of a reversible equation to those written on the right.
The reaction in the direction that converts the original reactants into products.
Specification C5.3a · Paper 2 (Foundation), Paper 4 (Higher)
