List of top Chemistry Questions on Ideal and Non-ideal solutions asked in NEET (UG)

અભિકલ્પન A: પ્રવાહી P અને Q ના મિશ્રણથી બનેલા આદર્શ દ્રાવણ માટે, \( \Delta_{mix}H = 0 \) અને \( \Delta_{mix}V = 0 \) છે.
કારણ R: P અને Q વચ્ચે કોઈ આંતરક્રિયા થતી નથી.

Assertion A : For an ideal solution formed by mixing liquids P and Q, \(\Delta_{mix}H=0\) and \(\Delta_{mix}V=0\). Reason R : No interactions occur between P and Q. In the light of the above statements, choose the most appropriate answer from the options given below.

अभिकथन A :
तरल P और Q के मिश्रण से बने एक आदर्श विलयन के लिए, \[ \Delta_{mix}H=0 \] और \[ \Delta_{mix}V=0 \] होता है।
कारण R :
P और Q के बीच कोई अन्योन्यक्रिया नहीं होती है।
