1) The rate constant for a reaction is increases with temperature T. The activation energy for the reaction is 98000J/mol. By what factor will the rate constant increase when the temperature is increased from 300 K to 310 K (Hint: Solve for the ratio of k>/kg) 2) Half-life of a reaction: For the first order reaction 2N2Os(g) O2(g) + 4NO2(g) the half-life is 693 s at 45 C and at the half-life at 65C is 70.7 s. a) Calculate the time taken for 35% of the reaction to be completed at at 45 C Value of k: Integrated rate law: Time: b) Calculate the activation energy for the reaction given the information 3) Which of the following changes with temperature? (Circle one or more) A) Activation energy B) rate constant C) half-life of a reaction D) rate of the reaction
