Question
Consider the reaction : 3A + 2B → 4C
Initially, and at some fixed temperature, the reaction proceeds at such a rate that 2.3 millimoles of A are consumed in 1 minute and 12 secondes. The reaction takes place in 1 L.
The following table contains the experimental data for the reaction. (Taken from Ball.
| Rate (M/s) | [A], M | [B], M |
|---|---|---|
| 1.081 x 10-5 | 0.660 | 1.23 |
| 6.577 x 10-5 | 4.01 | 1.23 |
| 6.568 x 10-5 | 4.01 | 2.25 |
d. What is the order of the reaction.
e. Express the rate law and the integrated form equation. Is the reaction elementary?
f. If the rate constant k = 1.61x10-5s-1 and [A0] = 4M, find the period of time between the 12th and 13th half-life.
*g. If, for the same reaction, at the same temperature, we were to add a catalyst, would Ea, A, k and v be larger, smaller or equal? Explain.
