Answer 1

Explanation:

For the given reaction,

2 A(g) + B(g) → 2D (g)

Ang = 2-(3)

= -1 mole

Substituting the value of AU in the expression of AH:

AH = AU + AngRT

= (-10.5 kJ) - (-1) (8.314 × 10-3 kJ K-1 mol-¹) (298 K)

= -10.5 kJ -2.48 kJ AH-12.98 kJ

Substituting the values of AH and AS in the expression of

AGAGAHⓇ - TAS

= -12.98 kJ - (298 K) (-44.1 J K-¹)

= -12.98 kJ + 13.14 kJ

AG = + 0.16 kJ

Since AGO for the reaction is positive, the reaction will not occur spontaneously.
