If the temperature is increased by 10°C the rate of the reaction becomes:

Options

A. Ten times more
B. Ten times less
C. Two times more
D. Two times less

Answer

To solve the question regarding the effect of increasing the temperature by 10°C on the rate of a reaction, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Effect of Temperature on Reaction Rate**:
- According to the principles of chemical kinetics, an increase in temperature generally leads to an increase in the rate of a chemical reaction.

2. **Arrhenius Equation**:
- The relationship between temperature and reaction rate can be described by the Arrhenius equation, which states that the rate constant \( k \) increases with temperature. This is often summarized in the statement that for many reactions, the rate approximately doubles for every 10°C increase in temperature.

3. **Applying the 10°C Rule**:
- In this specific case, if the temperature is increased by 10°C, we can apply the rule that the rate of the reaction will double.

4. **Conclusion**:
- Therefore, if the temperature is increased by 10°C, the rate of the reaction becomes **2 times** the original rate.

### Final Answer:
The rate of the reaction becomes **2 times** when the temperature is increased by 10°C.
