Factors that affect enzyme reaction rate essay lab report factors that affect enzymes reaction rate name of lab: effects of temperature, ph, enzyme concentration, and substrate concentration on enzymatic activity introduction: enzymes are the most important types of proteins, they act as catalysis (speed up chemical reactions. Conduct your own science experiments with alka seltzer and find out how temperature affects the rate of reaction when in order for a chemical reaction to. Chemistry 12—experiment 18b—factors affecting reaction rate page 3 2 put the results for the calculations of [io 3-] in the table below: 3 for each trial, calculate “reciprocal time” reciprocal time is (1/reaction time) and the units are s-1 since time is inversely proportional to rate, reciprocal time is directly proportional to rate. Purpose: to understand the different factors that affect the rate of a chemical reaction the effect of temperature, concentration, surface area, and the presence of a catalyst.
Factors affecting rates of reaction thanks to michelle craig manitoba curriculum chemistry grade 12 kinetics, topic 3-08 objectives to design short experiments to investigate and explain qualitatively using collision theory the relationship between reaction rate and temperature, concentration, catalyst, and surface area. To understand the factors that affect reaction rates factors that influence the reaction rates of chemical reactions include the concentration of reactants.
