The molar gas constant (also known as the gas constant, universal gas constant, or ideal gas constant) is denoted by the symbol R or R. It is the molar equivalent to the Boltzmann constant, expressed in units of energy per temperature increment per amount of substance, i.e. the pressure–volume product, rather than energy per temperature increment per particle. The constant is also a combination of the constants from Boyle's law, Charles's law, Avogadro's law, a… WebThe formula is called the Arrhenius Equation... where A is the "Arrhenius constant" for the reaction, Ea is the Activation Energy, R is the gas constant, and T is the temperature. This form of the reaction isn't used much, and you'll only use it is you're given A, or asked to solve for A. More often, you'll use the equation indirectly to ...
Arrhenius originally considered A to be a temperature-independent constant for each chemical reaction. However more recent treatments include some temperature dependence - see Modified Arrhenius equation below.
