For a particular reaction at 123.3 °C, Δ?=−443.64 kJ , and Δ?=874.77 J/K . Calculate ΔG for this reaction at 3.2 °C. kJ
Let's first see what is given in the problem
01.G at temp123.3 °C = -443.64KJ
02.s value at 123.3° C = 874.77j/mol = 0.87477 KJ
03.temp = 123.3 °C = (123.3 +273.15) = 396.45 K
to find
G at 3.2 °C ( 276.35 K )
We know the formula
G = H - TS
putting the values given in the problem
-443.64 kj = H - (396.45× 0.87477)
H = -443.64 + 346.80
H = -96.83 KJ
Using this value to calculate G at 3.2 °C (276.35 K)
G = H -TS
G = -96.83 - (276.35 × 0.87477)
G = -96.83 - 241.74
G= -338.57 KJ
So the answer is -338.57 Kj at given temp .
