Question

Calculate the temperature at which each of the following reactions becomes spontaneous.

Compound ?H Calculate the temperature at which each of the following reactions becomes spontaneous. 2 NO(g) + Cl2(g) 2 NOCl(g) this reaction is (spontaneous above/spontaneous below) K PCl5(g) PCl3(g) + Cl2(g) this reaction is (spontaneous above/spontaneous below) K ClNO2(g) + NO(g) NO2(g) + NOCl(g) this reaction is (always spontaneous/never spontaneous) at all temperatures physically possible. Therefore, the reaction is (spontaneous above/spontaneous below) K

Explanation / Answer

delta G should be negative for spontaneous reaction.... and [delta G = delta H - T*(delta S)].

Using this equation calculate T ..

(ssrry for not giving the calculation part in the solution because of the slow net connection i cant able to upload the photo...pls rate me...i will upload asap.)
