For a first-order reaction, what should be plotted in order to observe a linear relationship? A. In[reactant] vs. time B. [reactant] vs. time C. 1/[ reactant] vs. time D. Not enough information Class Activity How can the rate constant for a zero-order reaction in A be determined? Aproduct A. From the slope of ln[A] versus time B. From the y-intercept of ln[A] versus time C. From the slope of [A] versus time D. From the y-intercept of 1/[A] versus time E. From the slope of 1/[A] versus time Class Activity Molecular iodine dissociates at 625K with a rate constant of 0.271s1. What is the half-life of this reaction? A. 1s B. 0.693s C. 2.56s D. 625s E. Not enough information Zeroordert1/2=2k[A]oSecondordert1/2=k0.693t1/2=k[A]o1 Class Activity A first-order reaction has a half-life, t1/2=315s. The time required for the reaction to be 65.0% complete is
