Equal masses of calcium trioxocarbonate(iv) were added to dilute hydrochloric acid at the temperature specified. Under which of the following conditions would the reaction be slowest?
Calcium trioxocarbonate ( iv ) chips a 20°C
CalcIum trioxocarbonate (IV) chips at 40°C
Calcium trioxocarbonate (IV) powder at 20'C
Calcium trioxocarbonate (IV) powder at 40'C
Correct answer is A
- Increasing the surface area of a reactant increases the frequency of collisions and increases the reaction rate.
- Chips have a lower surface area compared to powder, so it accounts for the slowest
