For the reaction,
`2A(g)+B(g) rarr 2D(g)`
`DeltaU^(Θ)=-10.5 kJ` and `DeltaS^(Θ)=-44.1 JK^(-1)`
Calculate `DeltaG^(Θ)` for the reaction, and predict whether the reaction may occur spontaneously.

Explanation

To calculate the standard Gibbs free energy change (ΔG°) for the reaction and predict its spontaneity, we can follow these steps:

### Step 1: Identify the given values
- ΔU° = -10.5 kJ (change in internal energy)
- ΔS° = -44.1 J/K (change in entropy)

### Step 2: Convert ΔS° to kJ
Since ΔU° is in kJ, we need to convert ΔS° from J/K to kJ/K:
