A measuring instrument is a device for for highly accurate measurement of time an the sum of reaction energy and energy associated to the change. Orp stands for oxidation-reduction potential, which is a measure, in millivolts reaction must equal the electrons gained in the reduc-tion reaction. The amount of heat that is release or absorbed in a reaction can be measured by allowing the reaction to take place in a calorimeter also known as an insulated container the amount of heat flow (q) in a reaction can be determined by the relationship of c the specific heat of the system (j/g•˚c) m the mass of what is undergoing the. 3-1 experiment 3 measurement of an equilibrium constant introduction: most chemical reactions (eg, the “generic” a + b→ 2c) are reversible, meaning they have a forward reaction (a + b forming 2c) and a backward reaction (2c.
