For a reaction at `25^(@)C` enthalpy change `(DeltaH)` and entropy change `(DeltsS)` are `-11.7 K J mol^(-1)` and `-105J mol^(-1) K^(-1)`, respectively. Find out whther this reaction is spontaneous or not?

Text Solution

AI Generated Solution

To determine whether the reaction is spontaneous at 25°C, we need to calculate the Gibbs free energy change (ΔG) using the following equation: \[ \Delta G = \Delta H - T \Delta S \] ### Step 1: Convert the temperature to Kelvin The temperature given is 25°C. To convert to Kelvin, we use the formula: ...
