Question

The temperature coefficient of a reaction is.

• A. Specific reaction rate at $25^{o}C$
• B. Rate of the reaction at $100^{o}C$
• C. Ratio of the rate constants at temperatures $35^{o}C$ and $25^{o}C$
• D. Ratio of the rate constants at two temperatures differing by $1^{o}C$

Answer 1

Answer: (C)

Ratio of the rate constants at temperatures $35^{o}C$ and $25^{o}C$

Answer 2

Temperature coefficient $\frac{K_{\text{3}\text{5}^{o}C}}{K_{25^{o}C}} = \frac{K_{308k}}{K_{298k}} = 2$ and 3 for

most reactions.
