Question

The reaction, A → products, is known to be zeroth order with respect to the concentration of A and zeroth order overall. The rate constant for the reaction is 0.1400 M·hr-1 at a certain temperature.

If the initial concentration of A is 0.750 M. What will be the concentration of A after 3.8 hr?
Answer M

How long would it take for 95.0% of the starting material (A) to undergo reaction?
Answer hr

Expert Solution
Step 1

The rate constant for the given zero-order reaction is = 0.1400 M·hr-1

The initial concentration of A is = 0.750 M

The concentration of A after 3.8 hr is =?

Required time to 95.0% of the starting material (A) to undergo reaction is =?
