Questions

For a chemical reaction R → P, the variation in the concentration (R) vs. time (t) plot is given as:

(i) Predict the order of the reaction.

(ii) What is the slope of the curve ?

(iii) Write the unit of rate constant for this reaction.

(iii) Write the unit of rate constant for this reaction.

Solution 1

(iii) Since it is a first order reaction, the unit of the rate constant is s−1.

Solution 2

For a chemical reaction R→P, the variation in the concentration (R) vs. time (t) plot is given as follows:

(i) The order of the reaction zero.

(ii) Slope = -k

Solution 3

(i) The variation in the concentration (R) vs. time (t) plot shown here represents a zero order reaction, for which the rate of the reaction is proportional to zero power of the concentration of the reactants.

(ii) For a zero order reaction, rate constant is given as

`k=([R]_0-[R])/t`

So, the slope of the curve for the variation in the concentration (R) vs. time (t) plot is equal to the negative of the rate constant for the reaction.

  Is there an error in this question or solution?
