Question

For an ideal solution, the correct option is:

• A. ${△}_{mix}S$ = 0 at constant T and P
• B. ${△}_{mix}V$ $\ne$ 0 at constant T and P
• C. ${△}_{mix}H$ = 0 at constant T and P
• D. ${△}_{mix}G$ = 0 at constant T and P

Answer 1

The correct option is C ${△}_{mix}H$ = 0 at constant T and P

For ideal solution,
${△}_{mix}H$ = 0
${△}_{mix}S$ > 0
${△}_{mix}G$ < 0
${△}_{mix}V$ = 0
