Given the concentrations, calculate the equilibrium constant for this reaction: pcl3(g) +cl2(g)⇌pcl5(g) at equilibrium, the molar concentrations for reactants and products are found to be [pcl3]=0.20 m, [cl2]=0.25 m, and [pcl5]=1.20 m. what is the equilibrium constant (kc) for this reaction? express your answer using two significant figures.

Thus the value of the equilibrium constant is

Explanation:

Equilibrium constant is the ratio of the concentration of products to the concentration of reactants each term raised to its stochiometric coefficients.

At eqm. conc.    (0.20) M    (0.25) M      (1.20) M

The expression for equilibrium constant for this reaction will be,

The figures in a number which express the value -the magnitude of a quantity to a specific degree of accuracy is known as significant digits.

Thus the value of the equilibrium constant is

neutrons are in the middle of the atom and the electrons, which are much smaller.

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.
