Final answer:
Chemical reaction rates are measured in concentration change per unit time, not in velocity units like m/s. They are affected by temperature and reactant concentration, according to specific rate laws.
Step-by-step explanation:
The question about the rate of reaction at 150°C cannot be answered with a rate expressed in meters per second (m/s), as that unit is used for measuring physical speeds, such as a sprinter running a certain distance over time, rather than chemical reaction rates. Instead, chemical reaction rates are typically given in terms of a change in concentration of a reactant or product per unit time, such as moles per liter per second (mol/L/s).
For example, if the initial concentration of a substance A is 1.00 molar (M) and it transforms into substance B, the rate could be expressed as a decrease in concentration of substance A over time. This could look something like a rate of 4.3 x 10-5 mol/L/s, which corresponds to a change in concentration of substance A as it reacts to form substance B.
Factors affecting reaction rate include temperature; as it increases, the reaction rate typically also increases. The relationship between reactant concentrations and reaction rates can be described by rate laws, which can tell us, for instance, that doubling the concentration of a reactant can double the reaction rate, indicating a direct proportional relationship between concentration and rate.
