A reaction, A + B → C + D + q is found to have a positive entropy change. The reaction will be (i) possible at high temperature (ii) possible only at low temperature (iii) not possible at any temperature (iv) possible at any temperature
Option 4) ΔG=ΔH−TΔS for the given reaction,deltaH=−ve as it is exothermic, ΔS=+ve, then ΔG=ve. So, the reaction will be spontaneous at all temperatures.
