Answer: a. Have an overall neutral charge
b. Have electrons that are not equally shared
d. Have slight positive and negative ends
Explanation:
Electronegativity is defined as the property of an element to attract a shared pair of electron towards itself.
A polar covalent bond is defined as the bond which is formed when there is a difference of electronegativities between the atoms. Example:
The more electronegative element i.e. chlorine acquires a partial negative charge as it withdraws the electron density towards itself. Thus hydrogen acquires a partial positive charge. The opposite charges cancel each other and thus overall it is electrically neutral.
The question has missing information.
The options are given below.
a.The equilibrium lies far to the right
b. The reaction will proceed very slowly
c. The reaction contains significant amounts of products and reactants at equilibrium.
d. The equilibrium lies far to the left
Answer : The correct answer is option c: The reaction contains significant amounts of products and reactants at equilibrium.
Explanation :
Option a is not correct because for equilibrium to lie far to the right, we need a large value of keq ( Keq >>> 1 ), but the keq value is small.
option b is also not correct because in order to predict the speed of the reaction, we need more information. The speed of the reaction cannot be predicted using Keq value.
Option d is not correct because for Keq to lie far to the left, it has to be very very small. ( Keq <<< 1)
The value of equilibrium constant is given as 4.24. This value is very near to 1.
Equilibrium constant for this reaction is calculated as
When Keq = 1,
That means concentrations of products and reactants are equal.
Since the keq value for our reaction is very close to 1, we can say that , there are significant amounts of reactants and products at equilibrium.
Therefore option C is the correct option.
