Chemical Reaction Rates

Reaction Rates

Reaction rates: the speed at which a reaction occurs over a given time interval

• know the formula

Observing Chemical Reactions

We can measure the rate of reaction by observing the concentration of the reactant and products over time

Average Reaction Rates

• Average rate of reaction: the change in concentration of a reactant or product per unit time over a given time interval.

• Calculated using the slope of the reaction:

m=y2−y1/x2−x1

• It should be calculated from each end point

Instantaneous Reaction Rate:

• The rate of a chemical reaction at a particular point in time.

• Calculated using the tangent line to the curve at that point and finding its slope.
