RATES OF REACTION

RATES OF REACTION

RATES OF REACTION. Rates of Reaction. The rate of a chemical reaction is the speed at which the reaction occurs (i.e. speed at which the reactants are used or products are produced). Rate can be measured by the: 1) change in mass of reactants or products . 2) change in pH

Chemical Reactions

Chemical Reactions

Chemical Reactions. And Enzymes. A chemical reaction is a process that changes, or transforms, one set of chemicals into another. Mass and energy are conserved Reactants become products Always involve changes in the chemical bonds that join the atoms of the compounds.

Reaction Spontaneity and Entropy

Reaction Spontaneity and Entropy

Reaction Spontaneity and Entropy. Thermochemical Reactions Lecture 3. Spontaneous Processes. A spontaneous process is a physical or chemical change that occurs with no outside intervention. However, for many spontaneous processes, some energy must be supplied to get the process started.
