Equilibrium Tes...

The equivalent conductance of $$M/32$$ solution of monobasic acid is $$8.0$$ mho $$cm^2$$ and at infinite dilution is $$400$$ mho $$cm^2$$. The dissociation constant of this acid is:

The total number of different kind of buffers obtained during the titration of $$H_3PO_4$$ with $$NaOH$$ are:

At what temperature liquid water will be in equilibrium with water vapour?
$$\Delta H_{vap} = 40.73 \ kJ \ mol^{-1}$$, $$\Delta S_{vap} = 0.109 \ kJ \ K^{-1} \ mol^{-1}$$, 

What will be the value of pH of $$0.01 mol\  dm^{-3} CH_3COOH (K_a = 1.74 \times 10^{-5})$$?

An acid $$HA$$ ionizes as, $$HA\rightleftharpoons H^++A^-$$. The pH of $$1.0$$M solution is $$5$$. Its dissociation constant would be:

At 373 K, steam and water are in equilibrium and $$\Delta H$$ = 40.98 kJ $$mol^{-1}$$.What will be  $$\Delta S$$ fro conversion of water into steam?
$$H_2O_{(l)} \rightarrow H_2O_{(g)}$$

A buffer solution with $$ pH =9 $$ is to be prepared by mixing $$NH_4CI $$ and $$ NH_4OH $$. Calculate the number of moles of $$NH_4CI $$ that should be added to one litre pf $$1.0 M $$ $$ NH_4OH $$ . $$[K_b = 1.8 \times 10^{-5}]$$

Consider the reaction equilibrium:$$2SO_2+O_2\rightleftharpoons 2SO_3$$ : $$\Delta{H}^0$$= -195 kJ on the basis of Le Chateliers principle, the condition favourable for the forward reaction is?

Strong electrolyte of the following is?
