In a spontaneous irreversible process the total entropy of the system and surroundings

In a spontaneouse irreversible process, the total entropy of the system and surroundings:

In a reversible process, if changes in entropy of the system and its surroundings are DeltaS_(1) & DeltaS_(2) respectively, then-

Entropy Change for System and surrounding

In a process, the value of the change in entropy of the system and its surroundings are x and -y J*K^(-1) . If xgty, then will the process be spontaneous?

In a spontaneous process the system undergoes
