Principle of maximum work — In the history of science, the principle of maximum work was a postulate concerning the relationship between chemical reactions, heat evolution, and the potential work produced there from. The principle was developed in approximate form in 1875… … Wikipedia
reaction mechanism — Introduction in chemical reactions (chemical reaction), the detailed processes by which chemical substances are transformed into other substances. The reactions themselves may involve the interactions of atoms (atom), molecules (molecule),… … Universalium
Reaction quotient — In chemistry, reaction quotient is a quantitative measure of the extent of reaction, the relative proportion of products and reactants present in the reaction mixture at some instant of time. For a chemical mixture with certain initial… … Wikipedia
reaction engine — An engine that works on the principle of Newton’s third law of motion: To every action, there is an equal and opposite reaction. All aerospace propulsions are based on this principle. Principle of reaction engine … Aviation dictionary
Principle of minimum energy — The principle of minimum energy is essentially a restatement of the second law of thermodynamics. It states that for a closed system, with constant external parameters and entropy, the internal energy will decrease and approach a minimum value at … Wikipedia
Reaction rate constant — In chemical kinetics a reaction rate constant k or λ quantifies the speed of a chemical reaction.[1] For a chemical reaction where substance A and B are reacting to produce C, the reaction rate has the form: Reaction: A + B → C k(T) is the… … Wikipedia
reaction, heat of — Amount of heat that must be added or removed during a chemical reaction to keep all substances involved at the same temperature. If it is positive (heat must be added), the reaction is endothermic; if it is negative (heat is given off), the… … Universalium
Reaction to the 1963 South Vietnamese coup — The reaction to the 1963 South Vietnamese coup that saw the arrest and assassination of Ngo Dinh Diem was mixed. Communist reaction The coup was immediately denounced by the Soviet Union and the People’s Republic of China, asserting that the coup … Wikipedia
Reaction engine — A reaction engine is an engine which provides propulsion by expelling reaction mass, in accordance with Newton s third law of motion. This law of motion is most commonly paraphrased as: For every action force there is an equal, but opposite,… … Wikipedia
