The Eyring Equation, also called the Eyring-Polanyi Equation, is used to calculate the rate of a chemical reaction at different temperatures in the field of chemical kinetics. It is written as k = (k_b[t])/h) * e^(-delta... More »

In a chemical reaction, the reaction rate is faster when there is a higher concentration of reactants because there are more molecules present that can collide with one another. Collision theory explains this phenomenon,... More »

The stoichiometric coefficient is the number written in front of each component of a balanced equation to indicate the amount of that component needed for the reaction. The stoichiometric coefficient is used in the calcu... More »

A balanced chemical equation allows a person to determine the molar ratios of reactants needed to carry out the equation to completion. A molar ratio takes into account the molecular weight of a substance when attempting... More »

A chemical property is a characteristic associated with a substance or reaction that is observable as it chemically changes or transforms into another substance. This chemical change produces a product that has a differe... More » Science Chemistry Atoms & Molecules

An exothermic reaction is a chemical reaction wherein energy is released in the form of light, heat, or sound. Reactions such as this can occur spontaneously. More » Science Chemistry Atoms & Molecules

Mass and atoms are the properties conserved in every ordinary chemical reaction. Because the atom is the smallest unit of matter, it is indivisible. Because atoms are indivisible, mass is neither created nor destroyed du... More »
