Question

What is the value of delta h and delta s for reaction to be spontaneous?

Answer 1

For a spontaneous reaction, the sign on Delta G must be negative. Gibbs free energy relates enthalpy, entropy and temperature. A spontaneous reaction will always occur when Delta H is negative and Delta S is positive, and a reaction will always be non-spontaneous when Delta H is positive and Delta S is negative
