Document Summary

The time to apply for summer positions is now, not in. Practice ps #1, you should be able to solve q 1 q 9. Remember: solving 2 questions per day is better than all problems in one day! Rate = k [a]m[b]n rate constant k m, n orders. 0. 050 find the order of rxn and the rate constant. Guess or take natural logarithm on both sides ln 4. 04 ln 2 = 2 ln 4. 04 = ln (2m ) = m ln 2. = 10. 4 m 1 min 1 units of k will change for different orders. Measure initial rates (rate at t = 0) Initial rate2 = k[a]2 m m rate1 rate2 m k [a]1. M knowing m, one concentration and its rate k. Order of rxn with more than one reactant. 4 clo2 + 4 oh 3 clo3. 6. 00 x 10 4 = 2. 5 = rate3 rate1. = 5. 5m n n = n n = n n n.
