Question

which of the following factors will slow down the rate of reaction? answer options: select one of four use as an enzyme decreased temperature increased surface area volume reduction

Explanation:

• Enzymes typically speed up reactions (catalysts), so "Use as an enzyme" increases rate.
• Decreasing temperature reduces the kinetic energy of particles, leading to fewer effective collisions, thus slowing reaction rate.
• Increased surface area provides more sites for reaction, increasing rate.
• Volume reduction (if for reactants in a solution or gas, it increases concentration) usually increases reaction rate.

Answer:

B. Decreased temperature
