Consider the following reactions:
A+ G <-> G
G + L <-> products
Reaction (1) occurs slowly; reaction (2) occurs very rapidly. The volumes of 0.20 MA, 0.40 M E, 0.00010 M L, and water combined in each trial, and the measured time, are shown in the table below. A kinetics study was done to determine the rate law for reaction (1) by carries out trials where aqueous solutions supplying A, E and L were combined, and the time in seconds required for the disappearance of all L added was measured. All trials were performed at room temperature.
Volume (mL) Used
Trial# A E L H2O Time(s)
1 10 10 2 8 100
2 5 10 2 13 25
3 10 5 2 13 140
4 10 10 1 9 49
5 5 5 2 18
1. Determine the order with respect to A and what is the order with respect to E?
2. Determine the value for the rate constant?
3. Calculate the expected time for trial 5? Explain.
4. Discuss how does trial 4 serve any purpose?
