Question
Transcribed Image Text:1) At a given temperature, a first-order reaction has a half-life of 155 minutes.
How many minutes elapsed after 75% of the reagent reacted?
2) What is the order of a reaction that has a single reactant and when plotting the logarithm values
(In) of the concentrations of that reactant against reaction time, it gives a straight line?
3) The reaction 21(g) → 12 (g) has a rate constant of 7 x109 M-¹ s¹ at 23°C. Calculate the half-life of
the reaction if the initial concentration of I is 0.60 M.
