Document Summary
Chm135h1 f - lecture 14 - chapter 13 (2) Example 1: f2 (g) + 2clo2 (g) -> 2fclo2 (g) Starting from general rate law: rate = k f2[ From experiment 1 and 2, can see that f2[ initial rate is also quadrupled. From experiment 1 and 3, can see that clo2 initial rate is also doubled. Find k : choose any one of the experiments and use its data k = rate. Be careful about units of k, since it represents the overall reaction order. Example 2: 2clo2 (aq) + 2oh- (aq) > clo3. If the initial rate is more complicated, compare rates to find m and n : rate 3 rate 2. 0. 00276 m/s k 0. 020 m k 0. 020 m. 0. 00276 m/s k 0. 060 m k 0. 020 m. Note that the rate constant k is different from example 1, since the overall reaction order is different.
