Kinetics and Equlibrium Problem Set
This problem set was developed by S.E. Van Bramer for Chemistry 146 at Widener University.
Given the reaction: R <--> 2 P
- Start with the following information:
- The forward reaction has
- Ea = 2 kJ/mole
- A = 0.01 s-1
- The reverse reaction has
- Ea = 4 kJ/mole
- A = 0.01 L mole-1 s-1
- Calculate the rate constant for the forward and reverse reactions at
- Calculate the rate of the forward and reverse reactions at 298 K and predict the direction of the net reaction when
- [R] = 0.1 M, [P] = 0.0 M
- [R] = 0.1 M, [P] = 0.1 M
- [R] = 0.1 M, [P] = 0.5 M
- [R] = 0.0 M, [P] = 0.1 M
- [R] = 0.2 M, [P] = 0.2 M
- Write an expression for
- the equlibrium constant for this reaction.
- the rate of the forward reaction.
- the rate of the reverse reaction
- At equlibrium, the rate of the forward and reverse reactions are equal. Combine the above expressions as appropriate and solve for the equlibrium constant K.
- Based upon the value for K at 298 K, calculate the equlibrium concentration of P when [R]=0.1 M. Calculate the rate of the forward and reverse reactions and predict the direction of the net reaction at these concentrations.
