Question

The temperature coefficient of most of the reactions lies between

• A. 1 and 3
• B. 2 and 3
• C. 1 and 4
• D. 2 and 4

Hint:

For most chemical reactions, the temperature coefficient ranges between 1 and 3, indicating a moderate increase in reaction rate with temperature.

Answer 1

The Correct Option is A

Step 1: Understand the temperature coefficient.
The temperature coefficient of a reaction indicates how much the rate of the reaction increases with a 10°C increase in temperature. For most reactions, this coefficient lies between 1 and 3.
Step 2: Analyze the options.
- 1 and 3 (Option A) is the correct range for most reactions. - 2 and 3 (Option B) would suggest a higher rate of reaction, which is uncommon for most reactions. - 1 and 4 (Option C) suggests an unusually high temperature dependence. - 2 and 4 (Option D) is also not typical for most reactions.
Step 3: Apply to the options.
The correct answer is (A) 1 and 3.
Final Answer: \[ \boxed{\text{1 and 3}} \]
