Question

For the reaction below, which statement best describes what is happening with the
sign of AGO?
NagP O4la q) + CrClaia q) – CrP O46) + 3 Na Cla q) (exothermic)
The reaction is non-spontaneous at low temperature and spontaneous at high
temperature.
The reaction is spontaneous at all temperatures.
O The reaction is spontaneous at low temperature and non-spontaneous at high
temperature.
O The reaction is non-spontaneous at all temperatures.

Expert Solution

Step 1

the reaction given is exothermic that means the change in enthalpy is -ve . now the entropy change is +ve in the reaction since 2mole of aqueous give 3mole of aqueous .

Now coming to the formula

change in free energy= change in enthalpy-temperature X change in entropy

Step by step

Solved in 2 steps
