Answer :
To determine the correct order of limestone reacting to form lime, from the slowest to the fastest, we need to consider how temperature affects the rate of chemical reactions.
1. Understanding Reaction Rates and Temperature:
- The rate of reaction is influenced by temperature. Generally, as the temperature increases, the rate of reaction increases. This is because higher temperatures provide more energy, allowing reactant molecules to move faster and collide more frequently with greater energy.
2. Analyzing the Given Options:
- Room Temperature: Reactions happening at room temperature tend to be slower because the energy available is relatively low.
- Heated to 100°C: When limestone is heated to 100°C, the reaction rate is higher than at room temperature, as the increase in temperature provides more energy for the reaction.
- Heated to 1600°C: When limestone is heated to a very high temperature like 1600°C, the reaction rate becomes much faster, as there is significantly more energy available for the reaction to occur.
3. Determining the Order:
- Based on our understanding, the slowest reaction occurs at room temperature, since it has the lowest energy.
- The next fastest reaction is at 100°C, which is faster than room temperature but not as fast as at 1600°C.
- The fastest reaction is at 1600°C, due to the substantial amount of thermal energy available.
4. Final Order from Slowest to Fastest:
- 1 pound of limestone at room temperature
- 1 pound of limestone heated to 100°C
- 1 pound of limestone heated to 1600°C
Therefore, the correct order from slowest to fastest, according to the rate of reaction in the formation of lime from limestone, is: 1 pound of limestone at room temperature; 1 pound of limestone heated to 100°C; 1 pound of limestone heated to 1600°C.
