### Activation Energy and Reaction Rates

**Reaction A** has a high activation energy, whereas **Reaction B** has a low activation energy.

**Which of the statements about reaction A and reaction B are true?**

- [ ] Reaction B is likely to occur at a faster rate than reaction A.
- [ ] Reaction A is likely to occur at a faster rate than reaction B.
- [ ] Reaction B is more likely to occur at all than reaction A.
- [ ] Reaction A is more likely to occur at all than reaction B.

**Explanation:**

Activation energy is the minimum amount of energy required for a chemical reaction to occur. Reactions with lower activation energy proceed faster and are more likely to occur under given conditions compared to reactions with higher activation energy. 

Thus, for reactions A and B:
- **Reaction B is likely to occur at a faster rate than reaction A** because it has a lower activation energy.
- **Reaction B is more likely to occur at all than reaction A** because the energy barrier for Reaction B is lower.

This understanding is essential for predicting reaction behaviors and rates in chemical processes.
