One of the primary visible emissions from a distant planet occurs at 494 nm. Calculate the frequency of this emission.

Spontaneity tell us the direction of the reaction, but not how fast it goes. gibbs free energy brings together enthalpy, entropy and temperature in one easy formula. g = h - ts. and, finally the sign of delta g is always negative for a spontaneous reaction.

Woah that’s a lot to read xd i’ll try though. i’ll get back t you if. i know the andwer
