I'll suggest the following way to remember the chemical equation;
Before you remember the chemical equation as whole, better remember the chemical formula itself with the name of chemical eg. Sugar is C6H22O11 or like just saying common salt rather remember it as NaCl. This will need some efforts nd patience at first, but as you practice it daily say while just waiting for bus or just sitting in bus or travelling you can try to remember it. This will make you familiarize the chemical composition of each of crucial and regularly used chemicals. Then while remembering chemical equation just say what are the chemical that are participating in the chemical reaction.
So for example if we have to remember the chemical reaction of Hydrochloric acid with Sodium Hydroxide . We must say like ' when Hydrochloric acid reacts with Sodium Hydroxide it gives you common salt and water'
So if we know the Hydrocholoric acid's & Sodium Hydroxide's composition then you can easily write the equation. The remaining thing is just balancing the equation. Even we can remember the balanced chemical equation like saying like
' when One part of Hydrochloric acid reacts with one part of Sodium Hydroxide it gives you one common salt and water'
NaOH + HCl ---> NaCl + H2O
Next about the reactions involving catalysts.
Here the only thing you need to remember is the change of product when a particular catalyst is used.Same as the above method, you try remembering that too.
Remember that this is not that hard to study.All it needs is a little attention.
Good luck
