Question
2. Consider the following reactions:
A -> B (1)
B + M -> C (2)
Assume M is present in great excess. The concentrations of B and C are zero at t =0.
(a) Write out the rate equations for A, B and C
(b) Assuming the pseudo-steady -state approximation for B, derive a set of equations for
the time dependent variation in concentration of A, B and C
(c) Make a sketch (plot) of the changes in concentrations of all three as a function of time.
Expert Solution
Step 1
In the given problem we need to first figure out the rate equations. Based on that the relation between the change in concentration of the substance with time needs to be calculated and finally plot this relation as a graph.
