During decomposition of an activated complex

a.  Energy is always released.

b.  Energy is always absorbed.

c.  Energy does not change.

d.  Reactants may be formed.

The correct choice among the given is -


1. (a, b)
2. (b, c)
3. (c, d)
4. (a, d)

Hint: Energy is always released, during decomposition of an activated complex

When the reactant molecules collide with each other they lead to the formation of an activated complex. It has the highest energy among reactants and product. When it decomposes to give product, energy is released and the stability of the product increases.

Since the entire concentration of the activated complex does not convert into products while some activated complex may give reactants also.
