1.	Standard thermodynamic conditions chosen for substance when listing or comparing thermodynamic data refer toA. one atmosphere pressure and `273 K`B. one bar pressure and any specified temperatureC. one atmosphere pressure and `298 K`D. one bar pressure and 298 K
Answer» Correct Answer - B For the ease of comparison and tabulation, we refer to thermochemical or thermodynamic changes under standard conditions. To indicate a change at standard pressure (1 bar pressure), we add a superscript zero. If some temperature other than `25^(@)C` (298 K) is specified, we indicate it with a subscript, e.g., `Delta H^(@)` (300 K). If no subscript appears, a temperature of `25^(@)C` (298 K) is limplied.
