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 »
