A) low temperature, high pressure and excess of ice
B) low temperature, low pressure and excess of ice
C) high temperature, low pressure and excess of ice
D) high temperature, high pressure and excess of ice
Correct Answer: D
Solution :
\[\underset{\begin{smallmatrix} (Greater \\ Volume) \end{smallmatrix}}{\mathop{Ice}}\,\underset{\begin{smallmatrix} (Lesser \\ Volume) \end{smallmatrix}}{\mathop{Water}}\,-X\,kcal(Endothermic\,reaction)\] In this reaction/volume is decreased. Therefore, according to Le-Chateliers principle, favourable conditions are (i) At high temperature, more water is formed as it absorbs heat. (ii) At high pressure, more water is formed as it is accompanied by decrease in volume. (iii) Excess of ice.
