题目In an experiment to study the effect of a catalyst on a chemical reaction rate, if the reaction rate with the catalyst seems to be no different from that without the catalyst, which of the following might be the cause? A. The catalyst was not in its active form, for example, it n...
An experimental investigation of the role of each possible catalytic effect is challenging, since experimental measurements reflect an integration over multiple effects. In this work, we present a review of our most recent research on some of the factors that can influence a chemical reaction in ...
Explain the following: a) Effect of catalyst on reaction rate. b Molecularity of chemical reaction.
A catalyst accelerates a reaction without being consumed, focusing on chemical processes; a cause is an event or condition that directly facilitates an effect, applicable broadly in various contexts.
