(Mass of $Li ^{3+}=8.3$ mass of proton)
$C (diamond) + O_2 \rightarrow CO_2(g)\ ;\Delta H =\ -97.6\ kcal$
$C (graphite) + O_2 \rightarrow CO_2(g)\ ;\Delta H =\ -94.3\ kcal$
The heat change for the conversion of $1\ g$ of $C (diamond) \rightarrow C (graphite)$ is

$(b)\ Bi^{+3} < Sb^{+3 }, Sn^{+2} < Sn^{+4}$
$(c)\ Pb^{+2} > Pb^{+4} , Bi^{+3} > Bi^{+5}$
$(d)\ Tl^{+3} < In^{+3} , Sn^{+2} > Sn^{+4}$
$(e)\ Sn^{+24} < Pb^{+2} , Sn^{+4} > Pb^{+4}$
$(f)\ Sn^{+2} < Pb^{+2} , Sn^{+4} < Pb^{+4}$
