2. Given the balanced equation representing a reaction:
Zn(s) + 2HCl(aq) - H2(g) + ZnCl2(aq)
Which set of reaction conditions produces Helg) at the fastest rate?
a. a 1.0-9 lump of Zn(s) in 50 mL of 0.5 M HCl(aq) at 20."
b. a 1.0-g lump of Zn(s) in 50 ml of 0.5 M HClag) at 30.C
c. 1.0 g of powdered Zn(s) in 50. mL of 1.0 M HCl(aq) at 20.00
d. 1.0 g of powdered Zn(s) in 50. ml of 1.0 M HClag) at 30.C
