The correct option among the following is:
and 
are wrong

is correct
and 
are correct 
is correct and 
is wrong
Text Solution
Verified by ExpertsB
Conductivity of an electrolyte is the conductance of 
of the given electrolyte. It increases with the increase in concentration of electrolyte due to increase in the number of ions per unit volume. Molar conductivity 
is the conductance of a solution containing 
mole of the electrolyte. It increases with the decrease of concentration due to increase in the total volume having one mole of electrolyte. Thus, interionic attraction increses and degree of ionisation decreases. Therefore, 
is wrong and 
is correct.
