Consider the zeroth order decomposition of A with an initial concentration of 4.5 M. If k= 0.0265 s1, what is the concentration of A after 45 seconds? Your Answer: Answer units Question 4 (5 points) Consider a first order decomposition reaction of A with t1/2 = 125.0 seconds. If the initial concentration was 0.50 M, what is the final concentration after 350.0 seconds? (Hint: Calculate k using the half-life equation, then use the correct integrated rate law.) Your Answer: Answer units Question 13 (5 points) If this reaction X + Y Z has the following reaction rate: rate = K[X][Y], when the concentration of X is doubled and the concentration of Y is also doubled, the reaction rate would be increased by a factor of: (If the reaction rate wont change, enter 1 :)) (type the number, do not spell it. For example enter "3" instead of "three") Your Answer: Answer
