Given: CH:(e) = 2C[graphite) + H:(g) AG° = -209 kJ A sample of gaseous C,H; (acetylene, or ethyne) was stored for one year, yet at the end of this period the sample remained unchanged and no graphite or hydrogen gas had been formed. Briefly explain why there is no inconsistency between the sign of AG° and the apparent stability of the sample.
