Title: To Investigate the Effect of Concentration on the Rates of Diffusion. What is the relationship between concentration of hydrochloric acid and the rate of diffusion? Abstract The research question that this report is going to discuss is “What is the relationship between concentration of hydrochloric acid (HCl) and the rate of diffusion?” My hypothesis for this research question is that change in rate of diffusion will be observed when the agar

Demonstration of the Rates of Reaction Between Sulphuric Acid (25mL ±0.5mL) and Magnesium (0.02g ±0.01g) Changing Due to Different Surface Areas By Chania Baldwin Introduction: When sulphuric acid and magnesium are added together‚ magnesium sulphate and hydrogen gas is created. To create such a reaction the atoms must collide with a sufficient amount of energy. Every reaction requires a different amount of energy to create the reaction‚ which is called the activation energy; when there is not enough

Melissa Carrithers AP Chemistry 12/17/14 Rate Law Determination Pre-Lab Purpose: The purpose of this lab is to observe the reaction between sodium hydroxide and crystal violet so that the order of the reaction could be determined along with the rate constant‚ k‚ and the half-life for this reaction. Hypothesis: If the reaction between crystal violet and sodium hydroxide reacts appropriately‚ then the order will be first order. Procedure: Mix 10 mL of sodium hydroxide and crystal violet solution

Lab Report: How Temperature affects Reaction Rate Aim: The Aim is to investigate how temperature can affect Reaction Rate. The experiment will be performed by heating equally sized and weighted lime stones with equal amounts and concentration of Hydrochloric acid at different temperatures. The temperatures will be 35˚C and 40˚C. We will measure the reaction rates by observing gas release of the reaction between lime stones and Hydrochloric acid. The amount of gas release at different

Competitor Case Study - HCL Technologies Submitted by: Farah Aijaz PGP20121663 SUMMARY HCL has grown faster than Indian IT Industry during the last decade.While HCL growth was lagging behind Indian IT Industry growth during the first half of the decade‚ HCL came back strongly during the second half of the decade. During the first half of the decade‚ HCL revenues grew at a 5-year CAGR of 30% from $207mn in FY2000 to $764mn in FY2005. While HCL Technologies (HCL) was rising at 30% compound

Purpose: To determine the effect of various factors on the rate of reaction between an enzyme andits substrate‚ and also to determine the optimal ranges under which the enzyme activity ismaximized. Also to determine whether saline and alcohol are inhibitors or activators Hypothesis: PH factor prediction: I predict that as the pH increases so the activity of the enzyme willincrease until it reaches optimum pH range (pH 7) because the enzyme is less denaturedwhen it reaches the preferred pH level
