A) \[{{G}_{ice}}>{{G}_{{{H}_{2}}O}}\]
B) \[{{G}_{ice}}<{{G}_{{{H}_{2}}O}}\]
C) \[{{G}_{ice}}={{G}_{{{H}_{2}}O}}=0\]
D) \[{{G}_{\,ice}}={{G}_{\,{{H}_{2}}O}}\ne 0\]
Correct Answer: D
Solution :
When water and ice are at equilibrium at temperature \[0{}^\circ C, \,then \Delta G = 0\] where, \[\Delta G = {{G}_{ice}} - {{G}_{water}}\]\[{{G}_{ice}} - {{G}_{water}}\,\,=\,\,0\]\[\Rightarrow \,\,\,\,\,\,\,\,\,\,{{G}_{ice}} = {{G}_{water}}\,\,\ne \,\,0\]
