How catalyst increase rate of reaction
Web8 de abr. de 2024 · Answer: Positive catalyst: A positive catalyst is considered a catalyst that improves the reaction rate. By accepting a narrower path, such a catalyst reduces … 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.
