Prediction: I predict that the higher the concentration the faster the rate of reaction will be because when the higher the concentration the more particles there are to collide with the acid. ...
Theory: Rate of Reaction, amount of a substance that takes part in a chemical reaction in a given time. ... An iron catalyst speeds up the reaction and makes the process fast enough to be economically worthwhile.
Other factors change reaction rates. If reacting substances are heated, the rate of the reaction usually rises; conversely, if they are cooled, the reaction slows down. ...
Increasing the concentration of reactants (the amount dissolved in a given volume of solution) can have an effect similar to heating them, because the more particles present, the more likely a collision, and so the higher the reaction rate. ...
Particle size can also affect reaction rate. ... The rate of reaction increases as the concentration increases.
