Temperature and Reaction Rates

These flashcards cover key terms and concepts related to the effect of temperature on reaction rates.

Reaction Rate

The speed at which a chemical reaction occurs, influenced by factors like temperature.

Hypothesis

A proposed explanation made on the basis of limited evidence as a starting point for further investigation.

Anomalous Result

A data point that deviates significantly from the other results in an experiment.

Independent Variable

The variable that is changed or controlled in a scientific experiment to test its effects on the dependent variable.

Dependent Variable

The variable being tested and measured in a scientific experiment.

Collision Theory

Theory that states chemical reactions occur when particles collide with sufficient energy and proper orientation.

Precipitate

A solid that forms and settles out of a liquid mixture during a chemical reaction.

Fair Test

An experiment where only one variable is changed at a time while all others are kept constant.

Temperature (°C)

A measure of how hot or cold something is, which can affect reaction rates.

Cloudy Mixture

A turbid solution resulting from the formation of solid sulfur during the reaction of sodium thiosulfate and hydrochloric acid.
