yes,there must be equlibrium
all reactions are equilibrium
Equilibrium occurs when the forward and backward reactions happen at the same rate
If you can solve the beam reactions by the equations of equilibrium, then it is statically deterrminate. If not, that is, more unknown reactions than the equations of equilibrium, then it is indeterminate, and you need to know something about its deformation to solve the reactions.
Equilibrium.
Equilibrium expressions cannot be written for complete reactions, because you have to have the forward rate, as well as a reverse rate. Complete reactions do not have reverse rates, because they become complete, and all of the reactants are used up. Complete reactions only produce products, and the products don't produce reactants. word count for answer: 52
The forward and backward reactions are equal.
I believe all reactions chemical and biological reach a state of equilibrium- I was a t a lecture on Thursday conducted by some of the best scientists in the world, and one of them was some kind of chemist- don't remember what kind, and he showed us all a reaction which switched colours all the time, like it couldn't make up its mind which colour to stay on after he'd put in several different liquids; and he said this substance after a while will eventually reach equilibrium and will stay on one colour. So in conclusion, I believe that all, not most, biological and indeed chemical reactions all eventually reach a state of equilibrium.
True
They catalyse both the forward and reverse reactions, so the position of equilibrium is unaffected. The system will however reach equilibrium more quickly.

The forward and backward reactions are equal.
In a particular time, if the forward and backward reactions of a reversible reactions take place in the same rate, there would be not a visible change (i.e. no net change) in the system, and that system is said to be at equilibrium.
