If a molecule has four hybrid sp3 orbitals, it can be concluded that the molecule has a TETRAHEDRAL GEOMETORY
Answer: The value of Keq for the reaction expressed in scientific notation is 
Explanation:
Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios.
For the given chemical reaction:

The expression for
is written as:
![K_{eq}=\frac{[NO]^2\times [Cl_2]}{[NOCl]^2}](https://tex.z-dn.net/?f=K_%7Beq%7D%3D%5Cfrac%7B%5BNO%5D%5E2%5Ctimes%20%5BCl_2%5D%7D%7B%5BNOCl%5D%5E2%7D)


The value of Keq for the reaction expressed in scientific notation is
