Rule of thumb gives the activation energy of most organic reactions as approximately 50 kJ/mol. Based on that, calculate by what factor the reaction rate increases when the temperature climbs from 25°C to 45°C.

1. 3.6
2. 3.2 x 1046
3. 1.001
4. 1.3

do the calculation, verify 3.6 I did it in my head
