A slightly bruised apple will rot extensively in about 3.5 days at room temperature (26.0 °C). If it is kept in the refrigerator at certain temperature, the same extent of rotting takes about 14 days. If the activation energy for the rotting reaction is 3.78 x 104 J/mol, calculate (i) the temperature (in °C) that the refrigerator must be set to in order to have the same extent of rotting, and (ii) the collision frequency factor (A) for the rotting reaction at room temperature. (HINT: Take the rate constants, ks, to be 1 apple/3.5 days for room temperature & 1 apple/14 days for the unknown temperature.) Be sure to use all the digits in "273.15" when converting between °C to K. DO NOT use "273". i) Temperature of the refrigerator = °c ii) Collision frequency factor, A, at 26.0 °C (Give answer in sci. notation. See NOTE in ques. 1) = day1 A slightly bruised apple will rot extensively in about 3.5 days at room temperature (26.0 °C).
