The Effect of Concentration on Reaction Rate Essay - 874 Words.
The concentration of the hydrochloric acid will be changing each time to test if it speeds up a reaction. The speed for the light intensity to drop by 10% will be measured after each attempt so that the affects of concentration changes can be recorded.
I also predict that the change in concentration of reactants affects the rate of reaction proportionately and hence, the order of reaction. Such that, if the concentration of the reactants is reduced by half, the rate of reaction will also decrease by a certain proportion.
In this experiment, the effect of enzyme concentration is chosen to be investigated on the rate of reaction catalysed by enzyme catalase. An increase in enzyme concentration will increase the active site available and thus increase the rate of reaction until it reaches maximum velocity when all active sites of the enzyme molecules are engaged.

Effect of concentration on reaction rate According to the collision theory, the rate of reaction increases with the increase in the concentration of the reactants. As per the law of mass action, the chemical reaction rate is directly proportional to the concentration of reactants.
Increasing the concentration of calcium carbonate when there is already a lot in the solution will have no effect on the rate of reaction. Sometimes a reaction depends on catalysts to proceed. In that case, changing the concentration of the catalyst can speed up or slow down the reaction.
I predict that the higher concentration of the acid will have a much faster rate of reaction than the weaker solution, i.e. the mass loss will be more rapid. This is because a higher concentration of acid will contain more acid molecules per a set volume than low concentration solution.
How Concentration Effects the Rate of Reaction As the concentration of enzyme increases it will have an effect on the rate of reaction. The suggested optimum will be 10g as the higher the mass of catalase the more enzymes, meaning more space for reactions to occur.
Concentrations Affects on Reaction Rates - Concentrations Affects on Reaction Rates In the reaction between hydrochloric acid and magnesium, the hydrochloric acid will dissolve the magnesium and produce hydrogen gas. All chemical reactions involve reactants which when mixed do cause a chemical reaction which will make products.

Understanding How Concentration, Temperature, and PH Affect the Rate of Enzyme Reactions Tulsa Community College Abstract When the enzyme concentration increases, the rate of reaction will increase because there are lots of enzymes present to aid break down the substrate. However, a point will.
Effect of substrate concentration concentration on the rate of reaction” Introduction Enzymes catalyse biological reactions,increasing the rate of chemical reactions Enzymes have an affect on the structure of chemical transformation (stryer et al, 2011) Enzyme substances bind at the active cite which contains amino acid chains.
Note: The mathematical relationship between concentration and rate of reaction is dealt with on the page about orders of reaction.If you are interested, you can use this link or read about it later via the rate of reaction menu (link at the bottom of the page).
The effect of increasing the pressure on the rate of reaction. Collisions involving two particles. The same argument applies whether the reaction involves collision between two different particles or two of the same particle. In order for any reaction to happen, those particles must first collide.

Concentration of enzyme is also fairly easy to investigate, as you need to only increase the amount of potato that you want to investigate at a given time. Hypothesis As the concentration of enzyme increases it will have an effect on the rate of reaction.
The third is concentration, concentration speeds up the reaction rates as having more particles in the same area increases the likelihood in which they will collide.
Rates of reaction The speed of a chemical reaction is affected by temperature, concentration, particle size and the presence of a catalyst. It can be calculated by measuring changes in.
