An increase in temperatureby 10^(@) , canincrease the numberof collisions only by 2% , but therateof reactionincreases by 100%. Why? |
|
Answer» Solution :Temperature is directly proportional to kinetic energy. NUMBER of collisions is proportional to velocity or square root of temperature. However, in the Arrhenius rate expression, rate increases expone-ntionally but not linearly, with a change in temperature. The number of molecules exceeding the ACTIVATION energy approximately doubles by a `10^(@)` rise in temperature. HENCE rate increases by `100%`. |
