What is the difference between a spontaneous and Nonspontaneous reaction
7) spontaneous reaction occurs speedily.A spontaneous reaction which type of reaction is considered endergonic?Energy must be supplied to drive the reaction forward.It requires the influence of external factors in the form of energy or heat to proceed.And δs is the entropy change (in kj k−1mol−1) the enthalpy change can be calculated using a hess cycle if you don' know it, using enthalpy changes of other.
It has a positive free energy value.It is also a slower reaction.If e o(redox reaction) is positive, the reaction will proceed in the forward direction (spontaneous).Direction of ion flow 3.They can only occur if energy is put into the reaction from an external source.
Reactions can be either chemical reactions or biological reactions.Every reactant in a spontaneous process has a tendency to form the corresponding product.
