WebThe activation energy is what determines the kinetics of a reaction: the higher the energy hill, the slower the reaction. At the very top of the energy barrier, the reaction is at its transition state (TS), which is the point at which the bonds are in the process of breaking and forming. Web(ii) Considering the value of K p, calculate the final partial pressure of HCl(g) after the system inside the vessel reaches equilibrium at 400 K. . The value of K p is large, so the reaction will proceed to the right until the limiting reactant is essentially used up. Thus practically all of the CH 3 OH(g) will react and the final pressure of HCl(g) is 0.600 0.250 = 0.350 atm.

WebIf the rate of the forward reaction is greater than the rate of the reverse reaction, that means there's a net conversion of reactants to products. So therefore over time, the amount of reactants would decrease and the amount of products would increase. Eventually, the rate of the forward reaction becomes equal to the rate of the reverse reaction. WebThis problem has been solved!

Web27 Aug 2024 · Why are electrophilic substitution reactions of benzene slow? There are delocalised electrons above and below the plane of the ring. The presence of the delocalised electrons makes benzene particularly stable. Benzene resists addition reactions because that would involve breaking the delocalisation and losing that stability.
