For the reaction, A products, if the graph of [A] vs time gives a straight line, predict the order of the reaction.

Options

  1. APseudo first order
  2. BFirst order
  3. CSecond order
  4. DZero order

Correct answer

D. Zero order

Step-by-step solution

If the reaction is zero order, a plot of [A] versus t will produce a straight line with a slope that corresponds to the negative of the product of the rate constant and time, -k t and y intercept that corresponds to the initial concentration [A]₀ . Hence, the correct option is (4).
