For a hypothetical process, `A rarr B` , predict whether the process is spontaneous or not when.
(a) `DeltaH` is `+ve, T DeltaS` is` +ve` and `T DeltaS` is greater than `Delta `
(b) `DeltaH ` is `+ve` ,`T DeltaS` is `-ve ` and `T DeltaS` is equal to `DeltaH`
(c ) `DeltaH` is `-ve,T DeltaS` is `-ve ` and `T DeltaS` is greater than `DeltaH`
(d) `DeltaH ` is `-ve, TDeltaS` is `-ve` and`DeltaH` is greater than `T DeltaS`.
