How do reactant proportions affect the products of a chemical reaction?

Is it correct that if you alter the proportions of the reactants of many chemical reactions, especially step-wise, the products will change? Here is an example, please tell me if it is right or not:

KOH + H2SO4 ==> KHSO4 + H2O

2KOH + H2SO4 ==> K2SO4 + 2H2O

How do reactant proportions affect the products of a chemical reaction?

There are several factors that affect reactant's chemical reaction:
1. The concentration of reactants: Higher concentration of products tends to be associated with a lower reaction rate.
2. The temperature: A general thumb rule is the rate at which the reaction proceeds will get doubled for 10 degree Celsius increase in temperature.

3. Presence of catalyst: It lowers the energy of chemical reactants. Catalysts work by increasing the frequency of collisions between reactants, altering the orientation of reactants
4. Pressure: The increased pressure rate increases reaction rate.
