$(II)$ $2\,mol$ of $A$ and $2\,mol$ of $B$ in a $2\,L$ vessel
$(III)$ $0.2\,mol\, A$ and $0.2\,mol\,B$ in $0.1\,L$ vessel
Which reactant sample reacts by highest rate if reactant is in gaseous state and do not follow zero order reaction ?
Statement $I:$ The melting point of monocarboxylic acid with even number of carbon atoms is higher than that of with odd number of carbon atoms acid immediately below and above it in the series.
Statement $II :$ The solubility of monocarboxylic acids in water decreases with increase in molar mass.
Choose the most appropriate option
$(a)$ Lewis acidity order : $SiF_4 < SiC_{4} < SiBr_4 < Sil_4$
$(b)$ Melting point : $NH_3 > SbH_3 > AsH_3 > PH_3$
$(c)$ Boiling point : $NH_3 > SbH_3 > AsH_3 > PH_3$
$(d)$ Dipole moment order : $NH_3 > SbH_3 > AsH_3 > PH_3$
