I don't understand this at all really. Help would be much appreciated.


Zn(s)+2 HCl(aq)→ZnCl2(aq)+H2(g)

Zn(s) reacts with HCl(aq) according to the equation shown above. In trial 1 of a kinetics experiment, a 5.0g piece of Zn(s) is added to 100mL of 0.10MHCl(aq). The rate of reaction between Zn(s) and HCl(aq) is determined by measuring the volume of H2(g) produced over time. In trial 2 of the experiment, 5.0g  of powdered Zn(s) is added to 100mL of 0.10MHCl(aq). Which trial will have a faster initial rate of reaction and why?

Top Answer

The second trial will have a faster initial reaction speed. Remember that one of the factors that affects the... View the full answer
