Type: MCQ-conceptual-Medium-Class 12
Which of the following statements about the rate of reaction is correct?
A
Increasing the temperature generally accelerates most chemical reactions.
B
The rate of a reaction is solely determined by the concentration of reactants.
C
At lower temperatures, reactions proceed at the same rate as at higher temperatures.
D
The rate of reaction remains constant regardless of external factors.
Correct Answer
Option A
Detailed Explanation
Increasing the temperature generally accelerates most chemical reactions, as seen in the examples of N2O5 decomposition and KMnO4 decolourisation. This is highlighted in the NCERT context, indicating that reaction rates can significantly change with temperature variations.
