Question

Under what conditions a biomolecular reaction may be kinetically of first order?

Options

• When both reactants have same concentration.

• When one of the reacting species is in large excess. 

• When the reaction is at equilibrium 

• When the activation energy of reaction is less

Answer 1

When one of the reacting species is in large excess.

Explanation:

When one of the reacting species in a biomolecular reaction is in significant excess, the reaction is said to be a pseudo-first order reaction.
