. . . . . (Given that the value of solubility product of $A B \left( K _{ sp }\right)=2 \times 10^{-10}$ and the value of ionization constant of $H B \left( K _{ a }\right)=1 \times 10^{-8}$ )
$(A)$ Denaturation of proteins causes loss of secondary and tertiary structures of the protein
$(B)$ Denturation leads to the conversion of double strand of $DNA$ into single strand
$(C)$ Denaturation affects primary structure which gets distorted
$C(s)\, + \,C{O_2}(g)\, \rightleftharpoons \,2CO(g),$
the partial pressure of $CO_2$ and $CO$ are $2.0$ and $4.0 \,atm$, respectively, at equilibrium. The $k_p$ of the reaction is
$X_2O_4(g) \to 2XO_2(g)$
$\Delta U = 2.1\, kcal, \Delta S = 20\, cal\, K^{-1}$ at $300\, K$.
Hence $\Delta G$ is ....$kcal$
