An energy diagram for the dehydration of a Tertiary Alcohol is given. The reaction is acid catalyzed (heated with H2SO4). The question asks what Position B represents. Position B is the first stable intermediate that forms. The answer is that Position B (show below in the attachments) is ...
The comparison of prognostic models with Taylor's diagram revealed that Bayesian optimized support vector machine (BoA-SVM) was superior to Bayesian optimized boosted regression trees (BoA-BRT) for both TC and VST models. Building up a general selection strategy and catalytic performance prediction ...

The rational screening and prediction of MnOx-based catalysts that can stably catalyze OER in acid are summarized based on Pourbaix diagram analysis and thermodynamic density functional theory (DFT) calculations. Then, the up-to-date progress of upgrading the OER catalytic performance of MnOx-based ...
那么catalyst到底改变了什么?为什么它可以加速reaction?答案就是activation energy is decreased! 一般有两种常考的图来表现: Energy profile diagram Maxwell-Boltzmann energy distribution curve 满分回答:Adding a catalyst decreases the activation energy of a reaction. Hence, the fraction of particles possessing ene...
The triboelectric nanogenerator (TENG) is a new type of energy generator first demonstrated in 2012. TENGs have shown potential as power sources for electronic devices and as sensors for detecting mechanical and chemical stimuli. To date, studies on TENG
Label the activation enthalpy and the change in enthalpy ΔH on the diagram. Exothermic Reaction: A chemical reaction that releases energy is known as an exothermic reaction. This release of energy can either be in the form of heat or l...

Thus, both the products PV and RT have the dimensions of work (energy). A P-V diagram would show the equation of state in graphical form for several different temperatures. To illustrate the path-dependence of the work done, consider three processes connecting the same initial and final ...
Figure 1. Flow diagram of biodiesel production. 2.1. Biodiesel Production Biodiesel can be produced by various methods such as micro-emulsification, transesterification, pyrolysis, etc. It has been found out through extensive literature survey that the transesterification process (TP) is the most effect...
