1) For the reaction 2A + B products Determine the rate law and the rate constant, given the following data: [A] [B] Initial Rate 0.10 0.10 2x10 -2 0.30 0.10 1.8x10 -1 0.20 0.20 8.0x10 -2 2) For a first order reaction k = 0.00300 s -1 at 298 K. a) Determine the time in seconds required for 75% reaction (that means that 75% of the reactant has reacted) b) If the activation energy is 35.5 kJ/mol what is the rate constant at 350 K? 3) What is the rate law for the following mechanism? Cl 2 (g) 2 Cl(g) K 1 , fast Cl(g) + CO(g) COCl (g) K 2 , fast COCl(g) + Cl

Justify your answer. 5) Draw a reaction coordinate diagram (energy vs. progress of reaction) for an endothermic reaction. Label the transition state, the E for the reaction and the E a 6) Explain why raising the temperature increases the rate of reaction. Use a diagram showing the distribution of energies for molecules at high and low temperatures in you answer...
