A zero-order decomposition reaction starts with an initial concentration of 1.5 M and has a rate constant of 0.3 M/s. How long will it take to reach a concentration of 0.5 M?
💡 Hint: Set up the equation and solve for t based on the given information.
For a first-order reaction with a rate constant k = 0.07 s^-1, how long will it take for the concentration of reactant A to drop from 0.2 M to 0.05 M? Calculate the time and half-life.
💡 Hint: Plug in values step-by-step and don’t forget to find both t and half-life!
