Answer:
401.17 K is the minimum temperature at which the reaction will become spontaneous under standard state conditions.
Explanation:
The expression for the standard change in free energy is:
Where,
is the change in the Gibbs free energy.
T is the absolute temperature. (T in kelvins)
is the enthalpy change of the reaction.
is the change in entropy.
Given at:-
Temperature = 25.0 °C
The conversion of T( °C) to T(K) is shown below:
T(K) = T( °C) + 273.15
So,
T₁ = (25.0 + 273.15) K = 298.15 K
= 128.9 kJ/mol
= 33.1 kJ/mol
Applying in the above equation, we get as:-
= 0.32131 kJ/Kmol
So, For reaction to be spontaneous, 
Thus, For minimum temperature:-
<u>Hence, 401.17 K is the minimum temperature at which the reaction will become spontaneous under standard state conditions.</u>
Molar mass of aspirin =180. So, moles of aspirin = 500 × 1 0 − 3 / 180 = 2.78 × 1 0 − 3 = 278 × 1 0 −

Repulsion is a force or interaction among the atoms in a molecule in which the atoms REPEL one another. By the word itself repulsion, meaning to repel, it automatically bans the idea of ATTRACTION. Therefore, the statement above is FALSE. The answer to this question is "B. False".
