1.	Why do most chemical reaction rates increases rapidly as the temperature risesA. The fraction of molecules with kinetic energy greater than the activation energy increases rapidly with temperatureB. The average kinetic energy increases as temperature risesC. The activation energy decreases as temperature risesD. More collisions take place between particles so that the reaction can occur
Answer» Correct Answer - a As the temperature rises , the molecules gain more kinetic energy and more number of collisions takes place leading to speeding up of reaction i.e., increasing the rate of reaction .
