- Relate atomic structure to the periodic table of the elementsarrow_forwardUsing collision theory, indicate which of the following statements regarding physical nature of the reactants is true: a) physical nature of reactants The physical nature of reactants does not influence the rate of reaction because reactions happen only on the molecular level. Solids, liquids or gases all influence the rate of reaction the same because they are all in the physical state. Solid state reactants react faster if the particle sizes are larger because reactions occur at the boundary surface with direct contact. Gaseous-state reactions are faster than liquid-state or solid-state reactions because collisions between reactants are more frequent.arrow_forwardChlorine is an element with the symbol Cl.
