1 answer:

8 0

The answer is B. Suspension. Suspension mixtures are composed of two or more materials mixed together wherein the solute particles are usually larger than those found in a solution or colloid. In cases of solid-fluid suspension mixtures, the solid solute particles tend to settle at the bottom of the mixture after some time.

Aleonysh [2.5K]

The value for ΔG = 18 kJ/mol

<h3>Further explanation</h3>

Given

ΔH = 27 kJ/mol and ΔS = 0.09 kJ/mol.K

T = 100 K

Required

the value for ΔG

Solution

The spontaneous process of a reaction is based on 2 factors :

enthalpy change ΔH decreases and
entropy change ΔS increases

ΔG=ΔH-T.ΔS

$\tt \Delta G=27~kJ/mol-100\times 0.09~kJ/mol.K\\\\\Delta G=18~kJ/mol$
