Increasing substrate concentration increases the rate of reaction this is because more substrate molecules will be colliding with enzyme molecules , so more product will be formed however, after a certain concentration , any increase will have no effect on the rate of reaction, since substrate concentration will no longer be the limiting factor.
Objective: to analyze the effect of substrate concentration on the activity of enzymes theory: enzymes are protein molecules that act as biological catalysts by increasing the rate of reactions without changing the overall p.
