What unit can be used to measure the rate of a reaction?

The rate of a reaction is commonly expressed in terms of the change in concentration of reactants or products over time. In the given options, measuring the volume of gas produced or the volume of liquid consumed provides a clear indication of the reaction rate.

The cubic centimeters per second (cm³/s) unit signifies the volume change occurring in a reaction per second, which is applicable for reactions that produce or consume gases. This measure is essential for providing insight into how quickly a reaction is taking place.

For instance, if a reaction produces gas, measuring the volume in cm³ over a specified time allows you to quantify how rapid the reaction is, making it a suitable measure for reaction rates in various scientific experiments.

While other units like grams per minute or liters per minute can also measure different aspects of reactions (such as mass change or flow rate), they do not specifically focus on the change in volume directly linked to reaction rates involving gaseous products. Therefore, cm³/s is the most relevant unit for this purpose.
