The temperature in kelvin (K) in which the reaction occurs spontaneously is given as  349 K

What is entropy?

Entropy is simply defined as the measure of the degree of the disorderliness of a system. Mathematically, it can be expressed as:

ΔS = ΔH / T

Where

  • ΔS is the change in entropy of system
  • ΔH is the enthalpy change
  • T is the temperature

How to determine the temperature

  • Enthalpy change (ΔH) = +573 KJ/mol
  • Change in entropy (ΔS = +1.64 KJ/mol･K
  • Temperature (T) =?

ΔS = ΔH / T

1.64 = 573 m T

Cross multiply

1.64 × T = 573

Divide both side by 1.64

T = 573 / 1.64

T = 349 K
