Answer
Let's break down each statement about the rate of reaction to determine which are true.### Statement 1: Unit is
- **Explanation**: The rate of reaction is typically expressed in terms of concentration change over time. The common units are moles per liter per second (mol/(L·s)) or grams per second (g/s), but not seconds per gram (s/g).- **Conclusion**: This statement is **false**.### Statement 2: Dependent on the mass of product- **Explanation**: The rate of reaction depends on the concentration of reactants and products, temperature, and other factors, but not directly on the mass of the product.- **Conclusion**: This statement is **false**.### Statement 3: Can be calculated- **Explanation**: The rate of reaction can indeed be calculated using various methods, such as measuring the change in concentration of reactants or products over time.- **Conclusion**: This statement is **true**.### Statement 4: Dependent on the type of product- **Explanation**: The rate of reaction can be influenced by the nature of the reactants and products, as different substances react at different rates.- **Conclusion**: This statement is **true**.### Statement 5: Unit is
- **Explanation**: The rate of reaction can be expressed in grams per second (g/s) when considering the mass of reactants or products changing over time.- **Conclusion**: This statement is **true**.### Statement 6: Is an abstract concept- **Explanation**: The rate of reaction is a measurable quantity and not an abstract concept. It can be determined experimentally and has specific units.- **Conclusion**: This statement is **false**.### SummaryThe true statements about the rate of reaction are:1. **Can be calculated**2. **Dependent on the type of product**3. **Unit is
****Answer**: The true statements are:- Can be calculated- Dependent on the type of product- Unit is
