Worksheet: Rate Law Data and Rate Expressions 1. State the order with respect to each reactant and the overall order of the reaction for the following rate expressions: (a) rate = k [A] [B] (b) rate = k [A]2 [B] (c) rate = k [A] [B]1/2 2. If a first-order reaction has a rate constant of 10 s–1, what is its half-life? The half-life for a
The rate of the reaction S2O8 2– (aq) + 3 I– (aq) → 2 SO4 2– (aq) + I3 – (aq) doubles when either the concentration of iodide ions is doubled and the concentration of persulfate ions remains constant, or when the concentration of persulfate ions doubles and the concentration of iodide ions remains constant. a.
Determining reaction mechanism based on initial rate data 1. A reaction has the experimental rate law, rate = k[A]2. a. How will the rate change if the concentration of a is tripled? If rate 1 =k[A]2, then rate 2 =k[3A]2=32* k[A]2=9* k[A]2=9* rate 1. So the rate would be 9 times faster. b. How will the rate change if the concentration of A is ...

Worksheet # 1: Solve the Distance (d), Rate(r)/Speed and Time(t) Problems. Remember to read the problems carefully and set up a diagram or chart to help you set up the equations. Remember to use the right formula:
Speed, Distance, Time Worksheet. Use * m/s, km/h, or mph. Calculate Speed R̅= P 1. A car travels a distance of 540km in 6 hours. Calculate the speed of the car. 2. John is a runner. He runs the 100m sprint in 20.0 s. Calculate the John’s speed. 3. Lauren walks 400 m in 125 s . Calculate Lauren’s average speed. 4.
12 lip 2019 · distance = rate x time. When identifying the parts of the word problem, distance is typically given in units of miles, meters, kilometers, or inches. Time is in units of seconds, minutes, hours, or years. Rate is distance per time, so its units could be mph, meters per second, or inches per year.
