Investigating how the concentration of acid can affect the rate of reaction Background Magnesium + Hydrochloric acid ---> Magnesium chloride + Hydrogen Mg(s) + 2Hcl (aq) --> Mgcl2 (aq) + H2 (g) I intend to measure the rate of reaction by collecting the hydrogen gas produced and measuring the rate it is produced at. I am aware that hydrogen is produced when acid "particles" collide with magnesium atoms to produce hydrogen molecules. The variables which can affect the rate of hydrogen production are: * The state of the magnesium, for example whether its ribbon or a powder. * The volume of the acid. * The concentration of the acid. * Temperature. * The container that reaction is carried out in. The variable I will measure is rate calculated by measuring the volume of gas collected in a certain time. How do Variables affect collisions? * I think that if the magnesium is in powder form then the surface area is greater so...
