The equilibrium constant k for a certain reversible reaction is 1.32 × 10−4. which of the following is true for the reaction? the reverse reaction is more favorable than the forward reaction. the forward reaction takes place at a much faster rate than the reverse reaction. the equilibrium reaction mixture will have a very low concentration of reactants. the equilibrium reaction mixture will have a very high concentration of products.

The reverse reaction is more favourable than the forward reaction.

Explanation:

The value of equilibrium constant in this case is  .  A high value of equilibrium constant indicates that the forward reaction is more favourable.  

Thus the resultant of the reaction will have higher concentration of products.  When the value of equilibrium constant is less the reverse reaction will be more favoured than the forward reaction.

Thus the resultant of the reaction will have more reactants than products. Here equilibrium constant has a very low value which favours reverse reaction.

h let me think

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.
