NEET Chemistry (general) MCQ Question
Type: MCQ-conceptual-Medium-Class 12
Which of the following statements about the relationship between temperature, rate constant, and reaction rate are correct?
A
Increasing temperature results in an exponential increase in the rate constant.
B
The rate constant remains unchanged with varying temperature.
C
Decreasing activation energy will lead to a slower reaction rate.
D
The rate of a reaction is directly proportional to the rate constant at a given temperature.
Correct Answer
Option A
Detailed Explanation
According to the Arrhenius equation, increasing the temperature results in an increase in the rate constant, which in turn increases the reaction rate. Additionally, decreasing activation energy also contributes to a faster reaction rate, not slower.
