The compound 1, 3-di-t-butylcyclohexane exists in two forms that are known as the "chair" and "boat" conformations because the molecular structures resemble these objects. Equilibrium exists between these forms, represented by the equation chair boat At 580 K, 6. 42% of the molecules are in the chair form. Calculate the value of the equilibrium constant for the reaction as written above.

Cobalt-60 is an artificial radioisotope that is produced in a nuclear reactor and is used as a gamma-ray source in the treatment of certain types of cancer. if the wavelength of the gamma radiation from a cobalt-60 source is 1.00 × 10-3 nm, calculate the energy of a photon of this radiation.
