Question

Rate of reaction depends upon the surface area of the reactants.
(A) True
(B) False

Answer 1

Hint: A few reactions happen extremely quickly like the precipitation of silver chloride. It happens following blending fluid arrangements of silver nitrate and sodium chloride. Then again, a few responses are moderate like the rusting of iron within the sight of air and dampness. Some synthetic responses are neither moderate nor quick however occur at a moderate rate.

Complete Step By Step Answer
The assertion is true.
Pace of reaction relies on the surface region of reactants. By expanding the surface zone of the reactant, the pace of reaction increases because of more noteworthy contact between singular particles and furthermore because of the way that the surface atoms respond all the more rapidly. The surface territory expands the amount of the substance that is accessible to respond, and will along these lines increment the pace of the reaction.
The pace of response relies on the size of particles of the reactants. There are numerous critical elements which influence the pace of the response. What's more, the size of the particles of the reactants is one of such factors which influence the pace of response. The size of the molecule is contrarily corresponding to the surface territory of the molecule. Furthermore, the surface region of the molecule is straightforwardly relative to the pace of a substance response. That is the reason, we can say that the pace of the synthetic response is by implication subject to the size of the particles of the substance reactants.

Hence, option A is correct.

Additional Information
There are four principal factors that can influence the response pace of a substance response:
Reactant focus. Expanding the convergence of at least one reactant will regularly build the pace of response. This happens on the grounds that a higher convergence of a reactant will prompt more crashes of that reactant in a particular time-frame.
Actual condition of the reactants and surface region. On the off chance that reactant particles exist in various stages, as in a heterogeneous blend, the pace of response will be restricted by the surface territory of the stages that are in contact. For instance, if a strong metal reactant and gas reactant are blended, just the atoms present on the outside of the metal can crash into the gas particles. In this way, expanding the surface region of the metal by beating it level or cutting it into numerous pieces will build its response rate.
Temperature. An expansion in temperature ordinarily expands the pace of response. An expansion in temperature will raise the normal motor energy of the reactant particles. Accordingly, a more noteworthy extent of atoms will have the base energy essential for a successful impact.

Note
To comprehend the energy of compound responses, and the variables that influence energy, we should initially inspect what occurs during a response on the atomic level. As per the crash hypothesis of reactivity, reactions happen when reactant particles "viably crash." For an "viable impact" to happen, the reactant particles should be arranged in space effectively to encourage the breaking and shaping of bonds and the modification of iotas that bring about the development of item atoms
