Question

The main reason for the increase in reaction rate with temperature is that

possible Answers
1. heat acts as a catalyst.
2. the activation energy increases rapidly with temperature.
3. a 10°C temperature rise results in the rate doubling.
4. there is a dramatic increase in the number of collisions.
5. the fraction of high-energy molecules increases exponentially with temperature.

Answer 1

Posiible answers are

3. a 10°C temperature rise results in the rate doubling.
4. there is a dramatic increase in the number of collisions.
5. the fraction of high-energy molecules increases exponentially with temperature.

If we increase the temperature then kinetic energy of the molecules increases as kinetic energy is directly proportional to the temperature.

If energy increases then molecular motions also increases whic leads to increase in the number of collisions.

Every 10 degrees rise in temperature results in the rate doubling.
