For an ideal solution, the correct option is

• A

  ${\mathrm{\Delta }}_{mix}\mathrm{G}=0\text{ at constant }\mathrm{T}\text{ and }\mathrm{P}$

• B

  ${\mathrm{\Delta }}_{mix}\mathrm{S}=0\text{ at constant }\mathrm{T}\text{ and }\mathrm{P}$

• C

  ${\mathrm{\Delta }}_{mix}\mathrm{V}\ne 0\text{ at constant }\mathrm{T}\text{ and }\mathrm{P}$

• D

  ${\Delta }_{mix}H=0\text{ at constant }T\text{ and }P$
