Q1
A student tested how hydrochloric acid concentration affects the reaction time for a fixed mass of calcium carbonate. In each condition, 1.00 g of CaCO$_3$(s) was added to 50.0 mL of HCl(aq) at 22.0°C, and the time until fizzing stopped was recorded.
Data table:
- HCl (M): 0.50, 1.00, 1.50, 2.00
- Time until fizzing stopped (s): 180, 95, 62, 48
Which statement best describes the relationship between acid concentration and reaction time?
