Ammonia is prepared industrially by the reaction:
for the reaction: ΔH° = –92.2 kJ and K (at 25°C) = 4.0 × 10⁸. When the temperature of the reaction is increased to 500°C, which of the following is true?
a. At equilibrium, more NH₃ is present at 500°C than at 25°C.
b. The reaction of N₂ with H₂ to form ammonia is endothermic.
c. K for the reaction will be larger at 500°C than at 25°C.
d. Product formation (at equilibrium) is not favored as the temperature is raised.
e. None of these choices is true.

Both josef loschmidt and amedeo avogadro contributed to our understanding of basic molecular numbers, sizes, and reaction ratios. neither scientist discovered “avogadro’s number” in the form we use it today (6.02 x 10 23). still, there’s a controversy over the name. research the contributions from these two scientists and read about how avogadro’s number got its name. briefly state what you think this number should be called, providing key details of each scientist’s contributions to this concept and a solid rationale for your case in naming the number.

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.
