Le chatelier’s principle does not consider to be a source of stress to an equilibrium. a. temperature b. pressure c. solids d. gases e. catalysts

Option (E) is the correct answer.

Le Chatelier’s principle used to observe the effect of change in conditions such as pressure, temperature, and concentration on equilibrium.

Equilibrium state is affected by the change in temperature, pressure, and concentration. It also depends upon the state of matter i.e. solid, liquid and gas because change in temperature, pressure and concentration occurs according to state of matter.

Catalyst is used to increase the rate of reaction, no change in equilibrium state will occur due to catalyst.

Thus, Le Chatelier’s principle does not consider catalyst to be a source of stress to an equilibrium.

Changing the number of electrons will change the overall charge on an atom.

Explanation:

An atom that loses electrons will become positively charged and an atom with added electrons will become negatively charged. ... A charged atom is called an ion.
