The reaction is at equilibrium at 1,000 k. the equilibrium constant of the reaction is 3.90. at equilibrium, the concentrations are as follows. [co] = 0.30 m [h2] = 0.10 m [h2o] = 0.020 m what is the equilibrium concentration of ch4 expressed in scientific notation? .0059 5.9 x 10-2 0.059 5.9 x 102

Answer : The correct option is,

Solution : Given,

Equilibrium constant = 3.90

Concentration of = 0.30 M

Concentration of = 0.10 M

Concentration of = 0.020 M

The balanced equilibrium reaction will be,

The expression for equilibrium reaction will be,

Now put all the given values in this expression, we get the concentration of methane.

Scientific notation : It is the way of representation or writing the very large and the small number. In scientific notation, a number is written when a number between 1 and 10 is multiplied by the power of 10.

Therefore, the equilibrium concentration of methane is,
