The following reaction is done at
t = 25°c and p= 1.0 atm:

ca (s) + 2 hcl (aq) → cacl_2 (aq) + h_2 (g)

if 500.0 g of calcium are added to an excess of hci, what volume of h_2 is produced?

Reaction rate depends on how many molecules are coming into contact with each other with enough energy to react. increasing the temperature of the reactants will increase -
