A particular chemical reaction that produces hydrogen gas as a byproduct has an activation energy of 19.2 × 10⁻²⁰J. If the reaction produces 0.15 × 10⁻³ mol H₂/hr at room temperature (20°C), what is the rate of production of H₂ at 52°C?

Question

Quizplus · Accepted Answer

The rate of a reaction increases with increasing temperature. The activation energy is the energy barrier that must be overcome for a reaction to occur. The higher the activation energy, the slower the reaction rate. In this case, the activation energy is relatively low, so the reaction rate will be relatively fast. At a higher temperature, the reaction rate will be even faster.
