Question

At what temperature, a chemical reaction will have the following values of ∆G, ∆S and ∆H?

∆G = −5.2 KJ mol⁻¹, ∆H = 145.6 kJ mol⁻¹, ∆S = −216 kJ mol⁻¹

विकल्प

• 698.1 K

• 650.0 K

• 823.0 K

• 425.0 K

Answer 1

698.1 K

Explanation:

∆G = ∆H − T∆S

−5.2 = `145.6 - "T"(-216/1000)`

−5.2 − 145.6 = `(216  "T")/1000`

T = `-(150.8 xx 1000)/216`

T = 698.1 K
