Consider the following reaction at 298 K: 2H2S(g)+SO2(g)→3S(s, rhombic)+2H2O(g),ΔG∘rxn=−102 kJ Is the reaction more or less spon
Taya2010 [7]

Answer:

The reaction is  more spontaneous than under standard conditions.

Explanation:

  • For ΔG°rxn, when it is:

negative: the reaction is spontaneous in the forward direction.

zero: the reaction is at equilibrium.

positive: the reaction is non-spontaneous in the forward direction and spontaneous in the reverse direction.

  • Since (ΔG°rxn = − 102 kJ) negative value:

<em>So, the reaction is  more spontaneous than under standard conditions. </em>
