For zero order reaction which is true?

Option: 1

The rate constant is dimensionless.


Option: 2

Amount of the reactant remains the same throughout.

As we have learnt,

For a Zero Order reaction, the integrated rate equation is given as 

[\mathrm{A}]=[\mathrm{A]_{0}}-\mathrm{kt}

Comparing the above equation with the equation of a straight line, y = mx + c, if we plot [R] against t, we get a straight line as shown in the above figure with slope = –k and intercept equal to [R]o.


Therefore, option(3) is correct
