experiment is to determine the rate law and the activation energy for the reaction between persulfate ion‚ S2O82-‚ and iodide ion‚ I-: S2O82-(aq) + 2 I-(aq) 2 SO42-(aq) + I2(aq) The rate law can be written as Reaction rate = (1) Where m and n are the orders with respect to S2O82- and I-‚ respectively‚ and k is the rate constant. Determining the rate law involves determining the values of m and n. The temperature dependence of the rate constant is given by (2)

The purpose of this practical is to investigate how the pulse rate of humans changes when they exercise. Someone who is physically fit can supply their muscles with enough blood‚ carrying glucose and oxygen‚ for an activity at a lower heart and breathing rate. The fitter you are the lower your resting heart rate. You and your classmates will be the humans investigated. SAFETY: If you know you have any condition that affects you doing exercise‚ please make sure your teacher knows before you start

The Oceanic Corporation (Determining the Cost of Capital) Larry Stone wants to estimate the firm’s hurdle rate because it is a benchmark for how well the company needs to do on a project in order to at least break even. The higher the hurdle rate‚ the riskier the project will have to be and the lower the hurdle rate is‚ the safer the project will be for a company. A company should strive for a financing mix that minimizes the hurdle rate and matches the assets being financed. If there

Chapter 5: Flow Rate and Capacity Analysis 5.1 Objective Chapter 3 introduced the three basic building blocks of process flow namely the (average) flow time‚ (average) flow rate and (average) inventory. It is followed by a sequence of three chapters‚ 4‚ 5 and 6‚ which examine each one of these measures individually. Chapter 5 is concerned with flow rate analysis and issues of capacity. The major managerial concept discussed in the in the chapter is that of the bottleneck. We use the notion

Rate of Osmosis vs Solute Concentration Introduction: In nature‚ the quest to reach equilibrium‚ or the state of rest or balance due to the equal action of opposing forces (http://www.dictionary.com). Osmosis and diffusion are two ways that cells reach this equilibrium‚ without exerting energy. Due to the unique nature of the phospholipid bilayer‚ small molecules can pass through the semipermeable membrane easily‚ through diffusion (https://www.biologycorner.com). Water‚ however‚ has a slightly more
