AI Thread Summary
Scientists measure the reaction rate at the beginning of an experiment to establish a baseline when the concentrations of reactants and conditions are well-defined. This initial measurement is crucial for understanding the progress of the reaction, especially in slow reactions where the rate-determining step can significantly influence the overall rate. Observing the reaction from the start allows for accurate data collection and analysis. The initial rate provides insights into the kinetics of the reaction, helping to predict future behavior. Overall, measuring at the beginning is essential for reliable scientific analysis.

Homework Statement


Why do scientists take the rate of a reaction at the beginning of an experiment?


Homework Equations





The Attempt at a Solution


I would say because the amount of the reactants and present conditions are already known. But, there is a hint that says "think slow reactions." It may have something to do with the progress of the reaction?

well the slow step is the rate-determining step, and it would be wise to observe an experiment from the beginning ... so it might occur at the get go.
 

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
