For which substance and conditions can `DeltaS=0?`
(P) elements at 0 K (Q) compounds at 0 K
(R ) gases at 298K

Which of the following interhalogen compound is a gas at 298K?

Which substance has the greatest molar entropy at 298K?

Assertion (A) : For gaseous reaction when Delta n =0 , K_(p)=K_(c) . Deltan = change in the number of gas moles Reason (R ) : For gaseous reaction, K_(p)=K_(c)(RT)^(Deltan)

Equilibrium constant for a reaction 1.6xx10^(-6) at 298K. Calculate standard free energy change (DeltaG^(0)) and standard entropy change (DeltaS^(0)) of the reaction wat that pressure. Given, at 298K, DeltaH^(0)=25.34kJ .

The substance which possesses zero resistance as 0 K:

The pH of 0.001M sodium butanoate is 9.0 then the dissociation constant K_(a) for butanoic acid will be at "298K

Density of an ideal gas at 298K and 1.0atm is found to be 1.25kgm^(-3) .Density of the gas at 1.5 atm and at 298K is :
