Question

Q: Which method is used to measure conc. of reactants or products as a function of time?​

Answer 1

Answer:

Methods for measuring concentration

For gases, experimenters use a buret to measure the change in volume produced at different times. They then relate these volumes to changes in concentration. Chemists can also remove small samples of a reaction mixture at various times and analyze the concentration using titration

Answer 2

Answer:

• Reaction rate is calculated using the formula rate = Δ[C]/Δt, where Δ[C] is the change in product concentration during time period Δt.
• The rate of reaction can be observed by watching the disappearance of a reactant or the appearance of a product over time.
