5. A pharmaceutical lab tests the kinetics of a new drug, X in water. Experimental results show the reactions of X to follow first order kinetics: Rate = k [X] A. You prepared a 0.00500 molar solution of this new drug, which has a half-life of 3150 s at 25.0°C. What is the concentration of X after 2.50 hours? (8 points) B. The energy of activation of this reaction is also known. The Ea, energy of activation is 108.2 kJ/mole. What is rate constant at 35.0°C? (6 points) C. A possible mechanism that explains the decomposition of X into Y is given below: X →Y+B X+B B+Y i) Identify the rate determining step Identify any intermediates Does the mechanism explain first order kinetics? Explain with a proof. (4 points) (2 points) (2 points) E
