Webwhich is identical to the Rydberg equation in which R ∞ = k h c. R ∞ = k h c. When Bohr calculated his theoretical value for the Rydberg constant, R ∞, R ∞, and compared it with the experimentally accepted value, he got excellent agreement. Since the Rydberg constant was one of the most precisely measured constants at that time, this level of agreement … WebDec 23, 2011 · The second way to calculate Δ G is to use a formula that involves enthalpy, temperature, and entropy. The formula is below: Δ G is in the units Joules (J). Δ H is in the units of Joules (J). T is in the units of Kelvin (K). Δ S is in the units of Joules per Kelvin (J / K). However, again because all of these are linked to chemistry and ...
