molar mass
In chemistry, the molar mass M is a physical property defined as the mass of a given substance divided by the amount of substance
empirical formula
In chemistry, the empirical formula of a chemical compound is the simplest positive integer ratio of atoms present in a compound
chemical reaction
A chemical reaction is a process that leads to the transformation of one set of chemical substances to another
intermediates
A reaction intermediate or an intermediate is a molecular entity that is formed from the reactants and reacts further to give the directly observed products of a chemical reaction
rate-determining step
In chemical kinetics, the overall rate of a reaction is often approximately determined by the slowest step, known as the rate determining step or rate-limiting step
reaction mechanism
In chemistry, a reaction mechanism is the step by step sequence of elementary reactions by which overall chemical change occurs
limiting reactant
The limiting reagent in a chemical reaction is the substance that is totally consumed when the chemical reaction is complete
hydrate
In chemistry, a hydrate is a substance that contains water or its constituent elements
rate law
The rate law or rate equation for a chemical reaction is an equation that links the reaction rate with concentrations or pressures of reactants and constant parameters
