Question

5. Consider the reaction, N204(g) 2 NO2(8), where PNO2 0.29 atm and PN204 1.6 atm. For this reaction at these conditions, aG-_1000 J and ?G°-6000 J. which of the following statements a of the following statements about this reaction is(are) true? -1000J and a. The reverse reaction is spontaneous at these conditions. b. At equilibrium, Pw204, will be greater than 1.6 atm. c. The value of K for this reaction is greater than 1. d. The maximum amount of work this reaction can produce at these conditions is -6000J e. The reaction is endothermic.

Explanation / Answer

We know a relationship between ?G , ?G° and Q as ?G = ?G° + RTlnQ .

For forward spontaneous reaction, ?G should be -ve.. so this reaction is forward going with large k value. Option c is correct.
