Step 1
Step 1: The Gibbs Free Energy equation is given by: $\Delta G = \Delta H - T\Delta S$ where: $\Delta G$ is the change in Gibbs Free Energy $\Delta H$ is the change in enthalpy $T$ is the temperature in Kelvin $\Delta S$ is the change in entropy Show more…

For a reaction carried out at 298 K and 1 atm and for which ΔH° = +30 kJ/mol and ΔS° = +153 J/mol, determine if the reaction favors reactants or products. A) products B) reactants C) cannot be determined
Mahendra R.
For a certain chemical reaction, ΔH is > 0 and ΔS is < 0. This means that a. we conclude the reaction must be non-spontaneous regardless of temperature and becomes even more so at higher temperatures. b. we conclude the reaction must be spontaneous regardless of temperature and becomes even more so at lower temperatures. c. we conclude the reaction may or may not be spontaneous, but spontaneity is favored by low temperatures. d. we conclude the reaction may or may not be spontaneous, but spontaneity is favored by high temperatures. e. we cannot make any conclusion about spontaneity or even tendencies from the limited information presented.
Adi S.
Consider a reaction that has a positive ΔH and a positive ΔS. Which of the following statements is TRUE? A. This reaction will be spontaneous only at low temperatures. B. This reaction will be spontaneous at all temperatures. C. This reaction will be nonspontaneous only at low temperatures. D. This reaction will be nonspontaneous at all temperatures. E. It is not possible to determine without more information.
