Question

The rate of a chemical reaction depends on all the factors i.e. pressure, temperature, concentration, and catalyst.

Concentration: the rate of a chemical reaction is directly proportional to the concentration of the reactants i.e. if concentration increases the rate of reaction also increases and vice versa

Temperature: generally the rate of reaction increases with an increase in temperature as the colliding particles have enough activation energy to cross the energy barriers.

Pressure: pressure increases the concentration of the molecule which in turn increases the rate of reaction.

Catalyst: A catalyst increases the rate of reaction by providing an alternative path with lower activation energy.


Hence the correct answer is A, B, C, and D i.e  pressure, temperature, concentration, and catalyst.
