A chemist wishes to determine the rate of reaction of zinc with hydrochloric acid. The equation for the reaction is:
Zn(s) + 2HCl(aq) ---> H2(g) + ZnCl2(aq)
A piece of zinc is dropped into 1.00 L of 0.100 M HCl and the following data were obtained:
Time/Mass of Zinc
0 s/0.016 g
4 s/0.014 g
8 s/0.012 g
12 s/0.010 g
16 s/0.008 g
20 s/0.006 g
Calculate the Rate of Reaction in moles of Zn consumed per second.
