For a process in which ah is -298 kj and as is 100 j/k, calculate the change in the free energy at 0°c. a. -298 kj b. -325 kj c. -198 kj d. -271 k

b. -325 kJ

Explanation:

The expression for the standard change in free energy is:

Given that:

The conversion of T( °C) to T(K) is shown below:

T(K) = T( °C) + 273.15  

So,  

T = (0 + 273.15) K = 273.15 K

Also, 1 J = 10⁻³ kJ

So,  

Applying in the above formula as:

Option B is correct.
