temperature effect

Question

A 10°C rise in temperature doubles the rate of a reaction. The temperature coefficient of the reaction is:

RankGuru · Accepted Answer

The **Temperature Coefficient** of a reaction is defined as the ratio of rate constants at two temperatures differing by $10^\circ C$.
$	ext{Temperature Coefficient} = \frac{k_{T+10}}{k_T}$
- Given that the rate doubles for every $10^\circ C$ rise in temperature.
- Since Rate $\propto k$, then $\frac{Rate_{T+10}}{Rate_T} = \frac{k_{T+10}}{k_T} = 2$.
- Most chemical reactions have a temperature coefficient between 2 and 3.
