Which among the following affects the rate of reaction?
Concentration of the reactant
Physical state of the reactant
Activation Energy
All of the above
Rate of reaction depends on concentration of reactants, physical state of the reactants, surface area of the reactants, chance of collision of reactant molecules (temperature, volume & pressure), activation energy (catalyst to lower activation energy) etc.
