The practical activities needed in chemistry lessons. However, during the covid-19 pandemic, a suitable guide is needed. Therefore, that can involve students directly online learning and blended purpose of this study to determine feasibility Practical Guide for Determining Reaction Rate Order Based on Colorimeter® Application based expert judgement students’ response. This employs research deve...

In many chemical reactions, reaction rate fluctuations are inevitable. Whenever reactions occur, rates vary due to their dependence on the number of events or products. Accordingly, understanding impact product counting statistics is utmost importance when developing a quantitative explanation reactions. this work, we examine relationship between and fluctuations. Product uncover stochastic pro...
