Question

$S_1$ : All adiabatic processes are isoentropic processes.
$S_2$ : When $(\Delta G_{system}{)}_{T,P}<0$; the reaction must be exothermic.
$S_3$ : 'Radial nodes' can appear when radial probability distribution function become zero.

• A. T T F
• B. F F T
• C. T F T
• D. T F F

Answer 1

The correct option is B F F T

Only reversible adiabatic are isoentropic.
Endothermic reaction may be spontaneous if $\Delta S$ is positive.
