The volume of the solution increases on dilution, which results in decrease in specific conductance and thereby increase in molar conductance. Thus the correct option is D, i.e. specific conductance decreases and molar conductance increases.

Which of the following statements is correct with respect to the property of elements with increase in atomic number in the carbon family group 14 )?

Explanation: In carbon family stability +2 oxidation state increases on moving down the group in the periodic table with an increase in atomic number due to screening effect.

Which of the following statements is correct the rate of a reaction?

(iv) The rate of a reaction decreases with increase in the concentration of the reactant(s). The answer is the option (i). The rate of a reaction is defined as the change in concentration of the reactant per unit time.

Which of the following statement is correct a the rate of a reaction decreases with increase in concentration of reactant S B the rate of a reaction is independent of temperature change C the rate of a reaction is same at any point of time D the rate of the reaction decreases with passage of time as the concentration of the reactant decreases?

Answer: (a) Rate of reaction is defined as rate of decrease of concentration of any one of reactant with passage of time Thus, as the concentration of reactant decreases with passage of time, rate of reaction decreases.

Which of the following statement is correct for electrolytic solution upon dilution?

Conductivity of weak electrolytic solution decreases with dilution whereas equivalent conductivity, molar conductivity increases with dilution.

Which statement is correct about a strong electrolyte?

Which statement is correct about a strong electrolyte? The molar conductivity decreases significantly as the concentration increases. It is partially ionized in aqueous solution. Examples of strong electrolytes include CH3CO2H and Na[CH3CO2].

Which of the following statements are correct atomic size increases?

Atomic size increases down the group as the number of shells increase. Atomic size first increases and then decreases as the number of shells and effective nuclear charge both vary.

Which of the following is correct with increase in atomic size ionization energy increases?

We know that ionisation potential gradually decreases of moving down the group while atomic size increase as we move down the group. Hence, the larger the atomic size, the smaller is ionisation potential.

Which of the following statement is correct about half life of zero order reaction?

It is proportional to initial concentration for a zero order reaction. Average life = 1.44 times half life for a first order reaction. Time of 75% reaction is thrice of half life period in second order reaction.

Which reaction leads to an increase in entropy?

The entropy of the system increases during a combustion reaction. The combination of energy decrease and entropy increase dictates that combustion reactions are spontaneous reactions.
