In the presence of catalyst, iodide ion (I - ), the … Web19 de mai. de 2024 · C) It provides a lower activation energy for the reaction is the correct answer. Explanation: A catalyst increases the rate of the chemical reaction by lowering the activation energy for a reaction. Catalyst is used to increase the reaction rate, it remains unchanged in the chemical reaction and it does not change the equilibrium …
Web12 de fev. de 2024 · 1. Define Reaction Rate. 2. TRUE or FALSE: Changes in the temperature or the introduction of a catalyst will affect the rate constant of a reaction. For sample problems 3-6, use Formula 6 to answer the questions \[ H_2O \longrightarrow 2H_2+ O_2 \label{6} \] *Assume the reaction occurs at constant temperature. 3. WebAt room temperature, the rate of reaction is slower in the absence of catalyst with its activation energy being 76 kJ mol −1. In the presence of catalyst, iodide ion (I −), the reaction is faster since the activation energy decreases to 57 kJ mol −1.
