Consider the following generic reaction. a 2 b ( g ) − ⇀ ↽ − 2 a ( g ) + b ( g ) the initial concentration of a 2 b is 0.87 m and the initial concentrations of a and b are assumed to be zero. what is the equilibrium constant expression ( k c ) , if the equilibrium concentration of b is represented by x ?

Answer : The equilibrium constant expression will be

Solution :

Equilibrium constant : It is defined as the equilibrium constant. It is defined as the ratio of concentration of products to the concentration of reactants.

The given equilibrium reaction is,

Initially conc.     0.87          0           0

At equilibrium  (0.87-x)      2x          x

The expression of will be,

Therefore, the equilibrium constant expression will be

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
