If you react 2HCl +Zn -->Zncl2 + H2 and 2H2O2 -(catalyst)-> 2h2O + O2, which reaction will finish first? HELP

It depends on many factors:

- Is the Zn in powder form or a solid block?

- What is the concentration of the HCl?

- What is the concentration of H2O2?

- Are the two reactions take place at the same temperature or not?

All these factors are crucial to determine the speed of the two reactions.And, at last, we don't know anything about the quantities of the reactants.

it depends on the amounts. if they are considered to be equal, as long as i remember, the second reaction is faster, so it is going to be finished first

determine which is limiting reactant by converting the reactans to ZnCl2 (stoich) the reactant with smaller amt computed is the limiting and the smaller amt computes is the mass of ZnCl2
