Subscript is the text which a small letter/number is written after a particular letter/number. It hangs below its letter or number.
Answer:
C) low activation energy of forward reaction
Explanation:
Activation energy for the forward reaction is the quantity of free energy which is needed for a reaction to move from the reactant phase of energy level to the transition state of energy level. The higher the rate of energy level, the slower the chemical reaction.
Activation energy is a barrier that must be overcome for a reaction to take place.
Answer:
subscripts show the number of atoms of each type in the molecule.
Answer:
increases the frequency of particle collisions
Explanation:
One factor upon which the rate of reaction depends is the surface area of reactants.
According to the collision theory, reactions occur when reactant particles having the required (activation) energy collide with each other, this collision is inelastic. However, collision of particles having energies less than the activation energy results in elastic collisions and no chemical reaction.
The more the exposed surface area of reactants, the greater the number of particles that come into contact with each other and the more the chances of frequent effective collisions that lead to reaction.
Thus, powdered zinc reacts faster with hydrochloric acid than zinc strips
