Ammonia will decompose into nitrogen and hydrogen at high temperature. An industrial chemist studying this reaction fills a 75.0 L tank with 5.6 mol of ammonia gas, and when the mixture has come to equilibrium measures the amount of nitrogen gas to be 0.56 mol. Calculate the concentration equilibrium constant for the decomposition of ammonia at the final temperature of the mixture. Round your answer to 2 significant digits. K = 0

The rotational spectrum of CH* has been observed in the planetary nebula NGC 7027." The spectrum shows a series of lines separated by 29.64 cm1. Calculate the bond length of CH*. Take the reduced mass of CH* to be 0.9299 g/mol. Give your answer in angstroms with two decimal places. Answer:

With delta U being -24, what would w and q be in joules? I got w = -1913.43J and q as 1889.43J but it shows incorrect. Could you help show me how to calculate q and w for this problem?
