Question

Activation energy of a chemical reaction can be determined by ________

• A. Determining the rate constant at standard
• B. Determining the rate constant at two temperatures.
• C. Determining probability of collision
• D. Using catalyst

Answer 1

Answer: (B)

Determining the rate constant at two temperatures.

Answer 2

$\log\frac{k_{2}}{k_{1}} = \frac{E_{a}}{2.303R}\left\lbrack \frac{T_{2} - T_{1}}{T_{1}T_{2}} \right\rbrack$
