Draw an energy diagram for a reaction with {eq}K_{eq}=1 {/eq}. What is the value of {eq}\Delta G^{\circ} {/eq} in this reaction? Gibbs free energy: The standard Gibbs free energy change for a chemical reaction is related to the equilibrium ...
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 light ...
The enthalpy-direction factor diagram is proposed for energy and exergy analysis of chemical process systems. Focusing on the exchange of energy between the energy-donating processes and the energy-accepting ones, this diagram makes it possible to analyze systematically the effect of the distributed pa...
In endothermic reactions: The energy of the reactants is lower than that of the products. This type of reaction is represented by an "uphill" energy-level diagram. In an exothermic reaction: The energy of the products is lower than the energy of the reactants. Energeticallydownhill. 7.5: ...
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...

Schematic energy-band diagram of a donor-acceptor heterojunction. If both the excited (LUMO) and ground (HOMO) state of the donor material lie at energies sufficiently higher than those of the acceptor material, then it is energetically favorable for an exciton reaching the interface to dissociate...
Schematic diagram of a hydrogen-powered fuel cell. Anode and cathode are separated with the electrolyte, and two chemical reactions occur on the interfaces. The anode, for example, made out of platinum, breaks down the hydrogen fuel into electrons and ions. This increases the amount of ...
