Remember that enzymes are PROTEINS and therefore are subject to the physical characteristics as other proteins.
Temperature and pH levels affect all proteins. have you ever fried or boiled an egg? high temperatures and high acidity(low pH) changes the 3D protein configuration. Enzyme function is directly related to its 3D configuration.
the concentration of an enzyme is important because it affects the rate at which an enzyme acts/reacts with its particular substrate. Theoretically speaking, more enzyme concentration, faster reactions, faster effect

Generally an increase in concentration of substrate (the thing the enzyme catalyzes), enzyme and temperature all INCREASE the activity of the enzyme. There are limits though, increasing the concentration of a component so much that a solid forms will probably slow the reaction down, and increasing the temperature too much will denature and kill the enzyme activity.
pH is more difficult to describe as to how it will effect an enzyme, and usually there is some pH range that is specific to a specific enzyme. Some enzymes have broader ranges, some narrower. Some prefer acidic, some more neutral, some basic...

Actually the temperature doesn't have any affect on the concentration but it does speed up the rate at which they work by giving them more kinetic energy therefore they can move around faster and collide with substrates to react with them. However if the temperature is too high (Above 37 degrees - body temp) then this can break the bonds in the active site which changes the shape of the enzyme so the substrate no longer fits and so the enzyme becomes denatured.

those that you have listed are the factors that affect the activity of enzymes. increasing the concentration of enzymes would definitely increase their activity since more binding sites are present for the attachment of a ligand or of a substrate. the enzyme works more faster this way. however, if you have a low concentration, the opposite will work. but it does not mean that the enzyme could not function anymore, only slower, in this case. in terms of temperature, we know that most of the enzymes are proteins except the enzymes made of RNA. in the case of enzymes, when temperature rises up beyond its optimum level, the enzyme denatures, that is, it loses its original conformation, hence, it cannot perform its particular function. however, when the temperature is set back again to its functional state, the enzyme would also revert back to its native state, wherein it can assume again its role. temperature is just one of the denaturing agents. pH, on the other hand, affects enzyme in such a way like the temperature does. it may also denature the enzyme or it may even degrade the enzyme.

Concentration: the more enzymes and substrate the faster the reaction.
the warmer the temperature- the faster the reaction (matter moves faster when heated)
Too hot/cold: the enzymes denature ( disfigured and can't work anymore)
PH: too high or too low denaturing occures
