Chapter 19: Two Rates Experiments and Finding Rates

reaction mixture

Measure and record the temperature of the ________, and clean the apparatus as directed by a teacher.

sulfur

The ________ forms a cloudy yellow- white precipitate during the reaction.

Graphs

________ can represent rates of reaction.

solutions

a liquid mixture in which the minor component (the solute) is uniformly distributed within the major component (the solvent).

Faster rate of reaction

High concentration of acid

Reaction rate

Amount something in reacting

readings

taking amounts and recording them for later analysis

mean rate

all rates adding together and divided by amount

tangent

a straight line or plane that touches a curve or curved surface at a point, but if extended does not cross it at that point.

gradient

an increase or decrease in the magnitude of a property (e.g. temperature, pressure, or concentration) observed in passing from one point or moment to another.

reactant

Something that makes other substances react

intervals

Gaps between different events

mass

Amount of something in kg

solute

the minor component in a solution, dissolved in the solvent.
