have different demands in the current industry. The reaction rate of the reaction plays an important role in the production of the ester which could affect the production of the ester. Esterification is a reversible reaction and thus this affects the amount of ester produced as ester hydrolysis changes it back to its reactants. Very little data is available on how does the carbon chain length of carboxylic acid and alcohol affects the rate constant and equilibrium constant of esterification. Thus‚

Conversion Disorder Formerly known as "Hysteria‚" and also called Pseudoneurologic Syndrome‚ Hyterical Neurosis‚ or Psychogenic Disorder‚ Conversion Disorder is a type of Somatoform disorder. Symptoms occur that commonly resemble those of neurological disorders such as stroke‚ multiple sclerosis or epilepsy‚ but seemingly happen without corresponding bodily damage‚ and there are no existing physical disorders. Medical tests on people that have this disorder are either normal or they are unable

analysing the graph‚ you can see that there is a relation between the rate of reaction and the surface area. The larger the surface are‚ the faster the rate of reaction seems to be. However‚ although the grain with the largest surface area (the smallest grain) reached the highest point within the shortest amount of time‚ its end result was still lower then the medium sized grain. The explanation for this result is relatively easy. The rate of a chemical reaction can be increased by increasing the size

Introduction We are going to do an experiment to see how surface area effects the rate of reaction when added to hydrochloric acid. I will add calcium carbonate (marble chips) to hydrochloric acid. When calcium carbonate is added to hydrochloric acid a reaction takes place. The solution fizzes and gives off the gas carbon dioxide. I will collect this gas in a gas syringe and will time how long it takes for the reaction to produce 100cm3 of carbon dioxide. CaCO3 +2HCL Co2 +CaCl2 +H2O CalciumHydrochloricCarbonCalciumWater

The social rate of return to education looks at the positive externalities of schooling‚ e.g. faster innovation‚ enhanced productivity‚ and the accrued benefits for the entire community. To give an estimation of its magnitude‚ social costs and social gains of education must be considered. Costs comprise the public spending destined to education‚ that usually represents one of the top three public expenditure recipients. The benefits are the sum of the private returns for each citizen and the benefits

Declining Birth Rate Introduction Our country’s population is declining since the many campaigns were launched in order to allow citizens to not reproduce so rapidly. Singapore’s total fertility rate (TFR) has been on a general decline. The last time that the TFR of the resident population (comprising Singapore Citizens and Permanent Residents) was above the replacement level of 2.1 was in 1976. The resident TFR was 1.20 in 2011. Thus‚ we can conclude that Singapore’s total fertility rate has been

Then‚ among those numbers with conversion rates‚ I only looked at the numbers of which the amount is bigger than the cost. Otherwise‚ company is losing money whenever it pays advertising. Then‚ I multiplied average position with click through rate and conversion rate so that to calculate how people relatively choose to pick
