**Question:**Consider a reaction that has a negative ΔH and a positive ΔS. Which of the following statements is TRUE?**Options:**- ○ This reaction will be spontaneous only at high temperatures.- ○ This reaction will be spontaneous at all temperatures.- ○ This reaction will be nonspontaneous at all temperatures.- ○ This reaction will be nonspontaneous only at high temperatures.- ○ It is not possible to determine without more information.**Explanation:**In thermodynamics, the spontaneity of a reaction is determined by the Gibbs free energy change (ΔG), which is given by the equation: ΔG = ΔH - TΔS. For a reaction to be spontaneous, ΔG must be negative. When ΔH is negative (exothermic reaction) and ΔS is positive (increase in entropy), ΔG will be negative at all temperatures, indicating that the reaction is spontaneous at all temperatures. Therefore, the correct answer is:**○ This reaction will be spontaneous at all temperatures.**

For spontaneous reaction change in Gibbs free energy is negative

onsider a reaction that has a negative H and a positive S. Which of the following atements is TRUE? This reaction will be spontaneous only at high temperatures. This reaction will be spontaneous at all temperatures. This reaction will be nonspontaneous at all temperatures. This reaction will be nonspontaneous only at high temperatures. It is not possible to determine without more information.
