Although the dissolution of ammonium chloride in water is an endothermic reaction, even then it is spontaneous because

Answer»

`DELTA H` is POSITIVE , `Delta S` is -ve
`Delta H` is + ve, `Delta S` is zero
`Delta H` is positive, `T Delta S lt Delta H`
`Delta H` is +ve, `Delta S` is positive and `Delta H lt T Delta S`

Solution :EVEN if `Delta H gt 0`, if `Delta S gt 0 and Delta H - T Delta S lt 0` then spontaneous.
