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 Math / Science. The Arrhenius Equation, k = A⋅ e− Ea RT k = A ⋅ e - E a RT, can be rewritten (as shown below) to show the change from k 1 to k 2 when a temperature change from T 1 to T 2 takes place. The Activation Energy equation using the Arrhenius formula is: Ea = R⋅ ln(k2 k1) 1 T 1 − 1 T 2 E a = R ⋅ ln ( k 2 k 1) 1 T 1 - 1 T 2.
