Essay on the effect of concentration on the rate of a reaction - the effect of concentration on the rate of a reaction aim- our aim is to investigate the effect of concentration in the rate of a reaction method- below is a step-by-step guide to exactly what we did to do the experiment the first thing we did or we do in any experiment.

However, by increasing pnpp, the substrate, there are significant increases in the rate of reaction when the initial concentrations of pnpp are low, but when concentrations of pnpp are already high, increases in pnpp concentration resulted in little or no increase in the rate of production of pnp. The relationship between the rate of reaction and the concentration of the reactant is exponential which means that if the concentration doubles then the rate of reaction quadruples the rate of reaction is directly proportional to the concentration squared.
