🤓 Based on our data, we think this question is relevant for Professor Cruz's class at USF.

Solution: The reaction was monitored a function of time:A → B + CA plot of ln[A] versus time yields a straight line with slope -0.0045/s.a. What is the value of the rate constant (k) for this reaction at this temperature.b. Write the rate law for the reaction.c. What is the half-life?d. If the initial concentration of A is 0.250 M, what is the concentration after 225s? 

Problem

The reaction was monitored a function of time:

A → B + C

A plot of ln[A] versus time yields a straight line with slope -0.0045/s.

a. What is the value of the rate constant (k) for this reaction at this temperature.


b. Write the rate law for the reaction.


c. What is the half-life?


d. If the initial concentration of A is 0.250 M, what is the concentration after 225s?
