Select a concept
Select any concept, construction junction, or annotated relation by pointer, touch, search, or keyboard.
Construction junctions are diamonds. They show where multiple structures must coexist on the same carrier and satisfy compatibility conditions.
Move selected concept
Single-pointer and keyboard alternatives to dragging. Each activation moves the selected concept one step.
A product of activities raised to stoichiometric powers for the current state; comparison with the equilibrium constant indicates reaction affinity under stated conditions.

determines spontaneous response direction
Authored explanation
Comparison of reaction quotient with the equilibrium constant determines the thermodynamic direction of change; it does not predict the rate.
How to interpret this relation type
A theory, law, or interaction describes the behavior of the target within a stated regime. The edge detail must state important limits or qualifications.
