Which of the following statement is in accordance with the Arrhenius equation?
Options
- ARate of a reaction increases with increase in temperature
- BRate of a reaction increases with decrease in activation energy
- CRate constant decreases exponentially with increase in temperature
- DRate of reaction does not change with increase in activation energy
Correct answer
A. Rate of a reaction increases with increase in temperature
Step-by-step solution
According to Arrhenius equation [ k=A e^ -E_ s R T (1) ] Taking log of Eq. (1), we get [ k= A- E_ a R 1 T ] It is clear from the above equation that by increasing the temperature and by decreasing activation energy, the rate of reaction will increase.
