Formation of waterfrom its elements is spontaneous, butis slow. Comment . |
| Answer» Solution :Free energy decreases during the FORMATION of water from its elemnts. Hence, thermodynamically the reaction is SPONTANEOUS. Criterion of spontanity should not be correlated with time. Spontaneous reaction means that it will take place but how long it will take, thermodynamics does not tell. At ROOM temperature, without using a CATALYST, about `1%` of the reaction is complete in one YEAR. The reaction is slow. It is kinetically non-spontaneous. | |
