The ionization energy for sodium is 5.1 eV and electron affinity of bromine is 3.5 eV. Calculate the largest separation between Na and Br (as neutral atoms) for which they remain a bound molecule. Hint: the molecule will remain bound if the Coulomb energy of ions is lower than energy of neutral atoms. At the dissociation distance, the Coulomb energy between the ions is equal to the energy needed to create them our of neutral atoms:

Steam reforming of methane ( ch4) produces "synthesis gas," a mixture of carbon monoxide gas and hydrogen gas, which is the starting point for many important industrial chemical syntheses. an industrial chemist studying this reaction fills a 1.5 l flask with 3.5 atm of methane gas and 1.3 atm of water vapor at 43.0°c. he then raises the temperature, and when the mixture has come to equilibrium measures the partial pressure of carbon monoxide gas to be 1 .0 atm. calculate the pressure equilibrium constant for the steam reforming of methane at the final temperature of the mixture. round your answer to 2 significant digits.
