Macmillan Learning A reactant decomposes with a half-life of 173 s when its initial concentration is 0.162 M. When the initial concentration is 0.730 M, this same reactant decomposes with the same half-life of 173 s. What is the order of the reaction? 00

The decomposition of sulfuryl chloride at 320 degrees Celsius proceeds according to a reaction of order 1 with a half-life of 8.75h (see picture). Question 1: What is the value of the rate constant, K Question 2: What is the pressure of sulfuryl chloride 3.00h after the start of the reaction if the initial pressure is 96.2 KPa?

If the decomposition of reactant A follows first-order kinetics, what concentration of A remains if [A], = 0.273 M, k = 1.53 × 10-2 minutes-1, and the elapsed time = 1.61 hr? A) 0.009 M B) 0.273 M c) 0.109 M D) 0.0623 M

A first-order reaction (A → B) has a half-life of 25 minutes. If the initial concentration of A is 0.80 M, what is the concentration of B after 50 minutes? О 0.20 М O 0.30 M O 0.60 M О0.40 М

Radioactive decay of 212Bi is observed to be a first-order process with a half-life (t½) of 4.00 days.  It is noted that a 1.70 g sample of 212Bi decays over 12 days to leave only 0.213 g behind.  What is the rate constant (k) for this process?   a. 12.0 day–1   b. 0.250 day–1   c. 0.173 day–1   d. 5.77 day–1   e. none of these

If the reaction is first-order with a half-life of 3.0 minutes choose the correct pictures which represent the reaction mixture after  3.0 minutes and 6.0 minutes have elapsed

None

Consider two different first order reactions, A → B and XY The first reaction has a half life of 30 minutes. The second reaction has a half life of 60 minutes. Which has a smaller rate constant? If both are started with 3 moles of their respective reactants, which reacts more quickly? A reaction with second order kinetics starts with a concentration of 10.0 M and is run for 30.0 seconds. If the value of k is 0.00900 M¹s¹ what is the new concentration?
