Sample questions

Question 1

Hydrolysis of sucrose is given by the following reaction. \ce{Sucrose + H2O <=> Glucose + Fructose} If the equilibrium constant (K_c) is 2\times10^{13} at 300 K, the value of \Delta_rG^{\ominus} at the same temperature will be :

Question 2

For the reaction, \ce{2Cl(g) -> Cl2(g)}, the correct option is :

Question 3

Consider the following statements regarding enthalpy (H) and internal energy (U): I. For reactions involving only liquids and solids, \Delta H \approx \Delta U. II. For reactions involving gases where the number of moles of gaseous products is greater than the number of moles of gaseous reactants, \Delta H > \Delta U. III. The change in internal energy (\Delta U) of a system is given by q + w, where q is heat and w is work. IV. Enthalpy is an intensive property. Which of the above statements are correct?
