A chemical reaction is a process that leads to the chemical transformation of one set of chemical substances to another. Classically, chemical reactions encompass changes that only involve the positions of electrons in the forming and breaking of chemical bonds between atoms, with no change to the nuclei (no … See more Chemical reactions such as combustion in fire, fermentation and the reduction of ores to metals were known since antiquity. Initial theories of transformation of materials were developed by Greek philosophers, such … See more The general characteristics of chemical reactions are: • Evolution of a gas • Formation of a precipitate See more The elementary reaction is the smallest division into which a chemical reaction can be decomposed, it has no intermediate products. Most experimentally observed reactions are built … See more Chemical reactions are determined by the laws of thermodynamics. Reactions can proceed by themselves if they are exergonic, that is if they release free energy. The … See more Chemical equations are used to graphically illustrate chemical reactions. They consist of chemical or structural formulas of the reactants on the left and those of the products on the right. They are separated by an arrow (→) which indicates the direction and type … See more Most chemical reactions are reversible; that is, they can and do run in both directions. The forward and reverse reactions are … See more The speed at which reactions take place is studied by reaction kinetics. The rate depends on various parameters, such as: • Reactant concentrations, which usually make the reaction happen at a faster rate if raised through increased collisions per unit of time. Some … See more
