Experiment | Initial [A] | Initial [B] | Initial [C] | Initial Rate of Reaction |
1 | 0.1 M | 0.1 M | 0.2 M | 4 x 10^(-4) M/min |
2 | 0.3 M | 0.2 M | 0.2 M | 1.2 x 10^(-3) M/min |
3 | 0.1 M | 0.3 M | 0.2 M | 4 x 10^(-4) M/min |
4 | 0.3 M | 0.4 M | 0.6 M | 3.6 x 10^(-3) |
The method of initial rates is used to determine the rate law for reactants A, B, and C. This data was obtained at 25 degrees C. The overall stoichiometry of the reaction is A + B + 2C --> 3D.
1. What is a plausible rate determining step in this reaction?
2. In experiment 4, when the reaction has completed, which reactants, if any, will remain unconsumed? In what concentration?
3. In experiment 2, what is the maximum concentration obtainable for D? (assuming the volume remains constant.)
4. If experiment 2 is repeated at 50 degrees C and the initial rate is measured at 1.6 x 10^(-3) M/min. What is the activation energy of this new reaction?
