Spontaneous Reaction Video Lessons

Concept

# Problem: A reaction is spontaneous under a certain set of conditions. Select all equations that must be true for this reaction under these conditions: ΔGrxn &lt; 0, ΔGrxn &gt; 0, ΔGrxn = 0, ΔG˚rxn &lt; 0, ΔG˚rxn &gt; 0, ΔG˚rxn = 0, ΔHrxn &lt; 0, ΔHrxn &gt; 0, ΔHrxn = 0, ΔSrxn &lt; 0, ΔSrxn &gt; 0, ΔSrxn = 0, Q = K, Q &lt; K, Q &gt; K

Under nonstandard conditions:

$\overline{){{\mathbf{\Delta G}}}_{{\mathbf{rxn}}}{\mathbf{=}}{\mathbf{\Delta G}}{{\mathbf{°}}}_{{\mathbf{rxn}}}{\mathbf{-}}{\mathbf{RTlnQ}}}$

ΔG < 0 or ΔG = (–); the reaction is spontaneous

• ΔG = 0; the reaction is at equilibrium

• ΔG > 0 or ΔG = (+); the reaction is non-spontaneous
