increasing the concentration of reactant will increase the rate of a reaction.if a piece of magnesium ribbon is added to a solution of ethanoic acid the following reaction occurs.
magnesium + ethanoic acid = magnesium ethanoate
make a predication about what you think will happen when you react.Mg with different concentration of acid(0.5m,1.0m,1.5m,2.0m,2.5m) predict what the graph will look like.
explain your predictions using scientific theory ie collision/particle theory.

Collision theory predicts that rate of reaction will increase with increasing reactant concentration, because the higher the concentration the greater the number of particles and hence the greater number of collisions. If there are MORE collisions then the number (NOT the proportion) of successful collisions will also increase, therefore rate will increase.
So if you're plotting reaction rate vs acid concentration your graph will have a positive gradient and each incremental increase in concentration will have the same effect on the rate of reaction.
