Question
A student is investigating the reaction between nitric acid and calcium carbonate under different conditions. Which of the following changes would not cause the rate of the chemical reaction to increase?
Solution
Decreasing the temperature would not cause the rate of the chemical reaction to increase. In fact, it would likely slow the reaction down. This is because most chemical reactions happen faster when the temperature is increased. When the temperature is increased, the particles move faster and collide more often and with greater energy, which leads to an increased rate of reaction. Conversely, when the temperature is decreased, the particles move slower and collide less often and with less energy, which leads to a decreased rate of reaction.
