Question

chalk makes bubbles when it reacts with vinegar. what is the temperature for the flask that will react 2 cm of chalk with 50 ml of vinegar the fastest? 19 °c both will react at the same rate. 32 °c

Explanation:

In chemical reactions (like chalk - mainly calcium carbonate - reacting with vinegar - an acid), the reaction rate is influenced by temperature. According to chemical kinetics, generally, an increase in temperature leads to an increase in the reaction rate because higher temperature provides more particles with energy greater than or equal to the activation energy, resulting in more frequent and energetic collisions between reactant particles. Among the given temperatures, \(32^{\circ}\text{C}\) is higher than \(19^{\circ}\text{C}\), so the reaction will be fastest at \(32^{\circ}\text{C}\).

Answer:

\(32^{\circ}\text{C}\)
