Question

question 1 what are the units of reaction rate? options: l/min, atm/s, m/s, mol/hr

Explanation:

Reaction rate is the change in concentration (or amount) of reactants/products per unit time. Molarity (M, moles per liter) per second (M/s) is a common unit for reaction rate as it represents change in concentration over time. L/min is volume per time (not directly reaction rate), atm/s is pressure per time (for gas reactions but less common as standard), mol/hr is moles per hour (less common for rate expression which uses concentration change). So M/s is the unit of reaction rate.

Answer:

B. M/s
