Compound ΔG∘f (kJ/mol) A +387.7 B +550.7 C +402.0 Use the data given here to calculate the values of ΔG∘rxn at 25 ∘ C for the reaction described by the equation A+B↽−−⇀C If ΔH∘rxn and ΔS∘rxn are both negative values, what drives the spontaneous reaction and in what direction at standard conditions? ΔG∘rxn= kJ The spontaneous reaction is enthalpy-driven to the left. enthalpy-driven to the right. entropy-driven to the right. entropy-driven to the left.

Astable electron arrangement for an atom is one that does not easily change. how is this arrangement arrived at? a. valence electrons are transferred or shared to create a full outer shell of electrons. b. valence electrons are discarded into space to create a full outer shell of electrons. c. protons (positive charge) pair with valence electrons (negative charge) to create a strong bond. d. outer shells with valence electrons are transferred or shared.
