The order of a reaction depends upona) ...
Explanation:

The order of a reaction refers to the exponent or power to which the concentration of a reactant is raised in the rate equation. It determines how the rate of a reaction changes with respect to the concentration of the reactants.

Factors affecting the order of a reaction:
The order of a reaction can be influenced by various factors, including:

1. Pressure:
The pressure has no effect on the order of a reaction. It only affects the rate constant (k) of the reaction, which is different from the order.

2. Temperature:
The temperature also has no effect on the order of a reaction. It affects the rate constant (k) and the rate of reaction but does not change the order.

3. Molecularity:
Molecularity refers to the number of reactant molecules involved in an elementary step of a reaction. The molecularity of a reaction can determine the order of the reaction. However, the order of a reaction is not always equal to the molecularity.

4. Concentration of reactants:
The order of a reaction primarily depends on the concentration of the reactants. By conducting experiments and measuring the rate of reaction at different concentrations of reactants, the order can be determined. The order is determined by the rate equation or rate law, which is derived from experimental data.

The rate equation for a reaction with reactants A and B can be represented as:
Rate = k[A]^m[B]^n

Here, the exponents 'm' and 'n' represent the order of the reaction with respect to reactants A and B, respectively. These exponents can only be determined experimentally.

Therefore, the correct answer is option 'D' - concentration of reactants.
