Question

For a chemical reaction A + B = C + D &#916; r H &#920; = 80 &#160; kJ &#160; mol - 1 the entropy change &#916; r S &#920; depends on the temperature T (in K ) as &#916; r S &#920; = 2 T JK - 1 mol - 1 . Minimum temperature at which it will become spontaneous is K . (Integer)

Correct answer: 200

&#916;G &#176; = &#916;H &#176; - T &#215; &#916;S &#176; &#916;G &#176; = &#916;H &#176; - T &#215; 2 T T = 200 &#160; K

For a chemical reaction A + B = C + D Δ r H Θ = 80   kJ   mol - 1 the entropy change Δ r S Θ depends on the temperature T (in K ) as Δ r S Θ = 2 T JK - 1 mol - 1 . Minimum temperature at which it will become spontaneous is K . (Integer)
