Select the correct answer.

What can be inferred from the graph?

a graph of reactant and product concentration vs. time; a red curve shows the reactant decreasing and a blue curve shows the product concentration increasing with time; both curves intersect each other and diverge again; the chemical equation is A + B reacting to produce C + D

A.
The reaction reaches equilibrium at 2.75 seconds.
B.
The amount of reactant is greater than the amount of product at equilibrium.
C.
The reaction converts all the products back into reactants.
D.
The amount of reactants and products is equal at 14 seconds.
E.
The reaction between A and B is product favored.

A.  

The reaction between A and B is reactant favored.

B.  

The amount of product is greater than the amount of reactant.

C.  

The reaction uses all its reactants to form products.

D.  

The reaction reaches equilibrium at 1.5 seconds.

E.  

The amount of reactants is highest at equilibrium.

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.
