Solution

Heat has randomising influence on a system and temperature is the measure of average chaotic motion of particles in the system. The mathematical relation which relates these three parameters is $Δ S = \frac{q_{r e v}}{T}$
Here, $Δ S$ = change in entropy
$q_{r e v}$ = heat of reversible reaction
T = temperature
