What happens when Delta G is positive? Unfavorable reactions have Delta G values that are positive (also called endergonic reactions). When the Delta G for a reaction is zero, a reaction is said to be at equilibrium. Equilibrium does NOT mean equal concentrations. If the Delta G is positive, the reverse reaction (B ->A) is […]
