1. The problem statement, all variables and given/known data At room temperature (20°C) orange juice gets spoilt in about 64 hours. In a refrigerator at 3°C juice can be stored three times as long before it gets spoilt. Estimate (a) the activation energy of the reaction that causes the spoiling of juice. (b) How long should it take for juice to get spoilt at 40°C? (Answer: (a)43.46 kJ mol^(-1) (b) 20.47 hour) 2. Relevant equations 3. The attempt at a solution I guess I have to use the Arrhenius equation here but I don't have the rate constants at the two temperatures. How am I supposed to solve this?
