The plot of concentration of a reactant vs time for a chemical reaction is shown below. The order of this reaction with respect to the reactant is

Options

  1. A0
  2. B1
  3. C2
  4. Dnot possible to determine from this plot

Correct answer

A. 0

Step-by-step solution

For a reaction X ⟶ Y rate = - d [ X ] d t ; [ X ] = concentration of X If reaction is n th order, rate ∝ [ X ] n From the graph, the slope d [ X ] d t is constant. ∴ Rate is constant at any concentration. ∴ n = 0
