QJEEM25Chae17: JEE Main 2025 Chemistry - Class 11 JEEM25Chae17 Solution: The effect of temperature on spontaneity of reactions are…

The effect of temperature on spontaneity of reactions are represented as :

Δ\Delta H Δ\Delta S Temperature Spontaneity
(A) ++ −- any T Non spontaneous
(B) ++ ++ low T spontaneous
(C) −- −- low T Non spontaneous
(D) −- ++ any T spontaneous

The incorrect combinations are :

Multiple Choice Options

  • A (A) and (C) only
  • B (B) and (D) only
  • C (A) and (D) only
  • D (B) and (C) only

Step-by-Step Verified Solution

amp;∵ΔG=ΔH−TΔ Samp; For spontaneity of reaction : ΔG=−ve\begin{aligned}&\because \Delta \mathrm{G}=\Delta \mathrm{H}-\mathrm{T} \Delta \mathrm{~S}\\&\text { For spontaneity of reaction : } \Delta \mathrm{G}=-\mathrm{ve}\end{aligned}
