Question

Besides changing the temperature, what ELSE could you do to make this reaction happen FASTER?


add more antacid


add a catalyst


increase the pressure in the container


increase the surface area of the antacid by crushing it


ALL of the above

Answer 1

To make the reaction happen faster, all of the following suggestions could be effective:

1. **Add more antacid** - Increasing the concentration of the reactant can lead to a higher reaction rate.
2. **Add a catalyst** - A catalyst can speed up a reaction without being consumed in the process by lowering the activation energy required for the reaction to occur.
3. **Increase the pressure in the container** - For reactions involving gases, increasing the pressure can increase the concentration of the reactants, thus speeding up the reaction.
4. **Increase the surface area of the antacid by crushing it** - Smaller particle sizes lead to greater surface area, allowing more collisions between reactants, which can speed up the reaction.

Therefore, the correct answer is **ALL of the above**. Each of these methods can contribute to an increase in the rate of the reaction.
