What can we abserve from the reaction?what can we conclude from the experiment?
Concentration of reactants:Magnesium-Hydrochlor... acid system
1.the magnesium strip is add into different mole of Hydrochloric acid which is 6M, 4M, 3M and 1M.
2.Record the time for completion of the reaction.
Add the first magnesium strip to the 6M HCL solution,the time was recorded for all traces of the magnesium strip to disappear and repeat with 4M, 3M and 1M.

any reaction has diffrent rate equation,I don exactly no that what is the rate equation of this reaction .but I know that if the concentration of HCL is more (we have more no of mols and also no of intraction between particles increses) the rate increses.it is a overal answer for yr question.

The reaction rate should increase with increasing concentration of HCl. That is, the Mg strip should disappear fastest in 6M HCl. Is that what you observed? The "concentration" of Mg is the surface area of the strip, which is a constant in all trials.
