Answer :
Final answer:
The correct option is d) 118 °C. The chemical reaction is occurring at 118 °C. Understanding how temperature affects reaction rates is crucial in chemistry.
Explanation:
The correct option is d) 118 °C. The chemical reaction is taking place at 118 °C. To calculate how much faster a reaction proceeds at different temperatures, we consider that the rate of the reaction doubles for every 10 °C rise. At 45 °C, the reaction is 16 times faster than at 25 °C, and at 95 °C, it is 1024 times faster than at 25 °C. When a sample of NaClO3 is heated 20 °C higher, the decomposition would have taken approximately half the original time, as the rate doubles with every 10 °C rise in temperature.
