Q
Once a reacting system has reached equilibrium, it remains at equilibrium until it is distributed by some change of conditions
A
Distributing a system at equilibrium
6
Q
If a system at equilibrium is disturbed by changing its conditions (applying stress), the system shifts in the direction that reduces the stress
A
Le chatelier’s principle
7
