Correct Answer: Option B

Explanation

• Zero order - A horizontal line indicates that the reaction rate is independent of the reactant concentration.

The rate equation is: rate = k

• First order - A straight line passing through the origin signifies that the reaction rate is directly proportional to the reactant concentration.

The rate equation is: rate = k[X]

• Second order - A curved plot indicates that the reaction rate is proportional to the square of the reactant concentration.

The rate equation is: rate = k[X]2
