Consider the reaction of
A + B ==> C + D
From left to right is the forward reaction. From right to left is the reverse reaction.
So when A and B are producing C and D we are talking forward reaction. When C and D are reacting to produce A and B we are talking reverse reaction.
What is the difference between a forward and a reverse reaction? I am studying Lechatelier's principal and it states that with an increase in temperature it favors a reverse reaction and when the temperature decreases it favors a forward reaction. What does this mean exactly?
