Answer 1

Answer:

(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

[R] = [R]° – kt

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.
