Question

Which answer best describes the potential energy diagram for a reaction that takes place in water, if the temperature of the surrounding water is lowered?

Answer 1

the potential energy of the reactants is low; the potential energy increases gradually; it peaks, then decreases slightly

the potential energy of the reactants is high; the potential energy decreases gradually; then increases slightly

the potential energy of the reactants is low; the potential energy remains low; rapidly peaks, then rapidly falls

the potential energy of the reactants is low; the potential energy decreases gradually; then increases slightly
