WebDec 26, 2015 · S9.7b. First, you need to figure the half life of your compound. We do this by solving for k: t1 / 2 = 0.693 k. k = 0.693 t1 2. k = 0.693 2hrs = 0.3465. with this half life, we can find the time it will take by solving for t: ln [A] [A]o = − kt. We do not have the initial and final concentration, but that is okay. Web( 1) For a zero order reaction, t1/2 =[A0]/2K. As half life for zero order reaction is directly proportional to initial concentration, hence doubling the concentration of reactant, half life get doubled. 150 Share Still did not understand this question?

Talk to a tutor now WebSolution Verified by Toppr Correct option is B) For a zero order reaction, the expression for the half life period is t 21= 2k[A o]. Thus half life period is directly proportional to the initial concentration. When the concentration of the reactant is doubled, the half-life period is also doubled. Hence, the statement 1 is true. perry mason s1 e29
