Equilibrium Graph

When the forward and reverse reactions are occurring at the same rate, the reaction is said to be at:

• Chemical equilibrium

• Chemical reaction

• Chemical constant

• Chemical peace

Does the graph show positive or negative feedback?

• Positive, because when the red line shifts, the blue one does also

• Negative, because the blue line starts below equilibrium

• Negative, because the two actions are keeping each other near equilibrium

• Both positive and negative because the graph moves up and down
