environments affecting the rate of reaction‚ PNPP (p-nitrophenyl phosphate) + H20 ? PNP (p-nitrophenol) + H3P04. This reaction is catalyzed by the enzyme phosphatase. Different environments produced different reaction rates as environmental factors affect the efficiency of phosphatase. This is because environmental factors can change the tertiary structure of phosphatase‚ which alters its active site‚ and thus changes its efficiency to catalyze the reaction. We measured the rate of reaction‚ by using a chromogenic

Effect of Concentration on Reaction Rate Aim: To use a simple reaction between sodium thiosulphate and hydrochloric acid to discover concentration this determines how fast chemical reactions occur. Independent Variable: Concentration of hydrochloric acid (%) Dependent Variable: Time taken for chemical reaction to take place (sec) Hypothesis: My prediction is that the increased concentration of the thiosulfate will in turn lead to an increase in the rate of reaction. This is a well informed

Abstract We performed two trials of nine different variables of reactions to determine what increases/decreases reaction rates. The variables we used are hot/cold and room temperature water‚ a equal mixture of HCL and water‚ A equal mixture of NaOH and water‚ either a whole‚ broken‚ or finely crushed Alka-seltzer tablet. The fastest rate average was at 0.04 s (finely crushed Alka-seltzer with room temp. water). The slowest rate average is 8.02 s (Alka-seltzer with cold water). Introduction

Chemestry Lab Rates of Reaction (Picture from: http://sciencespot.net/Pages/kdzchem.html) The rate of reaction is how fast or slow a reaction is completed. This is important for factories and chemists all over the world. What happenes during a reaction is atoms or molecules that collide and form new molecules. You can affect this rate of reaction with: temperature of reactants or suroundings‚ surface area of reactants‚ if there is a catalyst present‚ but in theis lab the concentration was changed

Rates of Chemical Reaction II Pre-Lab Summary: First we will set up the experiment as shown in Figure 2‚ and then we will fill the trough with room temperature water and record the temperature and we will also add the room temperature water to the buret until it is about 10ml from the top. If there are no leaks in the apparatus‚ we will add 10ml of KI to 15ml of distilled water in a 125ml flask. We will swirl the flask so that it achieves room temperature‚ then we will add 5ml of H2O2 and quickly

The aim of this coursework is to scrutinize various IHRM strategies adopted by MNCs in the face of various environmental and institutional circumstances and to reveal the pros and cons of the seemingly neutral façade of the IHRM strategies. The layout of the coursework will be based on the ‘Eight-point star of IHRM: a framework of key aspects’ (Figure 1) which identifies the eight distinct and
