The temperature coefficient of a reaction is defined as:
- ASpecific reaction rate at $25\,^{\circ}C$
- BRate of the reaction at $100\,^{\circ}C$
- CRatio of the rate constants at temperatures $35\,^{\circ}C$ and $25\,^{\circ}C$
- DRatio of the rate constants at two temperatures differing by $1\,^{\circ}C$
