The surface area of a 2 cm x 2 cm cube is 24 cm2. If the 2 cm x 2 cm cube is cut in half, what is the sum of the surface area for both halves and how would it affect the rate of a chemical reaction?

Respuesta :

Answer:When the concentrations of the reactants are raised, the reaction proceeds more quickly. This is due to an increase in the number of molecules that have the minimum required energy. For gases, increasing pressure has the same effect as increasing concentration.

When solids and liquids react, increasing the surface area of the solid will increase the reaction rate. A decrease in particle size causes an increase in the solid’s total surface area.

Raising the reaction temperature by 10 °C can double or triple the reaction rate. This is due to an increase in the number of particles that have the minimum energy required. The reaction rate decreases with a decrease in temperature.

Catalysts can lower the activation energy and increase the reaction rate without being consumed in the reaction.

Differences in the inherent structures of reactants can lead to differences in reaction rates. Molecules joined by stronger bonds will have lower reaction rates than will molecules joined by weaker bonds, due to the increased amount of energy required to break the stronger bonds.
