Feasibility in Chemical Kinetics: Explained with Gamete Analogy
In the world of chemistry, especially in chemical kinetics, the word feasibility refers to whether a chemical reaction is likely to happen under certain conditions. Not all reactions that are possible on paper actually happen — they need the right energy, orientation, and timing.
๐ก What Does “Feasible” Mean?
A feasible reaction is one where the reactant molecules collide with sufficient energy and correct orientation to break old bonds and form new ones. If they don’t meet these conditions, the reaction will not happen — we call it infeasible.
⚛️ Real-World Analogy: Gametes Forming a Zygote
Just like in biology, where a male gamete (sperm) must meet a female gamete (egg) to form a zygote, chemical reactions also require the right “partners.” A sperm alone or an egg alone cannot create a new life — both must meet under the right conditions.
❌ What if Both Gametes are Same?
If both are male (sperm + sperm) or both are female (egg + egg), fertilization is impossible. Similarly, if two identical reactants cannot complement each other, the chemical reaction will be infeasible. This biological concept helps us visualize that reactants must be complementary in nature to react successfully.
๐ Conditions That Make a Reaction Feasible
- Collision: Reactants must collide
- Activation Energy: Collision must happen with sufficient energy
- Orientation: Molecules must align properly
- Concentration: More particles = more chances to collide
- Temperature: Increases kinetic energy of particles
- Catalyst: Lowers the activation
