For a chemical reaction to occur:
Correct answer: C. Reacting molecules must be properly oriented and energy more than or equal to Ea
- A. The vessel must remain open
- B. Reacting molecules should have less energy than Ea at time of collision
- C. Reacting molecules must be properly oriented and energy more than or equal to Ea
- D. The reacting molecules must not collide with each other
Explanation
In addition to having sufficient energy, reacting molecules must collide with the correct orientation.Proper orientation ensures that the reactant molecules come into contact in a way that allows the necessary chemical bonds to break and new ones to form, leading to the desired reaction.

About Reaction Kinetics
Reaction kinetics relates reaction rate to concentration, temperature, surface area and catalysts. Questions cover rate laws, reaction order, rate constants, activation energy and the activated complex, including how a catalyst lowers the activation energy without changing the overall energy change or equilibrium position.
