Question

-34, Examine LD: A the figure below: Which a. A letter represents the activated complex of the rate determining step? b. B -35. Given the following graph of rate vs. concentration, What must be the exponent of this reactant in the rate law for this process? d. 1/2 b. 1 36. Experiments were carried out to determine the effect of changing concentration on the initial rate of reaction for a given reaction. Given the data in the graph, what is the order of reaction with respect to this reactant? c. a.

Explanation / Answer

34) the point C ,represents the activated complex of the rate determining step ,it is the step that requires the highest energy during the reaction takes place . and hence ,the point C corresponds to the maximum energy requirement and in tern the activated complex

35) the graph clearly shows the rate remains constant throughout and hence it is a zero order reaction, as the rate doesnot change with change in concentration of reactant . answer a) 0

36) the graph represent y=C x^2 , where y represents the reaction rate and x represents the concentration so the rate vs concentration graph is of second order ,c)2
