The K for the reaction:

  +  <-------------->  2 lBr(g)

is 1.2 x . If the concentrations of all species are as follows: = 0.310 mol/L. = 0.310 mol/L and iBr(g) = 2.00 mol/L, is the system at equilibrium? not explain what must happen for equilibrium to be achieved.

Consider the following reaction at a particular temperature:

C₂H₄(g) + H₂(g) ↔ C₂H₆(g) Kc=0.99

If at some point in the reaction the concentrations of the chemical species are:

[C₂H₄]=0.146 M

[H₂]=0.317 M

[C₂H₆]=0.209 M

Is the system at equilibrium?

If not, what will the equilibrium concentrations of all chemical species be?

Hint: which species increase and decrease to reach equilibrium?

Calculate the concentrations of all species at equilibrium when 5.0 molar pure HOCL is placed in 2. Flask

thank you

can you provide formula aswell
