Sir,
In zero order reaction we write the slope to be
m=-k
But according to the eqn we get i.e., t=1/k([Ro]-[R])
Therefore the slope must be
m=1/k
Why dont we write it so.

Dear shruthi
Thanks for asking us a question in Ask the Expert section of TopperLearning.com.
Zero order reaction means that the rate of the reaction is proportional to zero power of the concentration of reactants.
At t = 0, the concentration of the reactant R = [R]0, where [R]0 is initial concentration of the reactant.
Comparing equation [R] = - kt + [R]0 with equation of a straight line, y = mx + c, if we plot [R] against t, we get a straight line with slope = –k and intercept equal to [R]0.
