alleryFor a chemical reaction, with a rise in temperature by 10°C, the rate of reaction typically:
ARemains unchanged
BBecomes nearly doubled (≈2×)
CHalves
DIncreases by 100×
Answer & Solution
Correct answer: B. Becomes nearly doubled (≈2×)
**Empirical rule of thumb:** rate roughly **doubles per 10°C rise** (the temperature coefficient ~2–3).
This is because more molecules cross the activation energy barrier at higher T.
