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. tattoo shops portland oregon

"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. " - This reaction is slower below than above

WebEnzymes are reusable. Enzymes are not reactants and are not used up during the reaction. Once an enzyme binds to a substrate and catalyzes the reaction, the enzyme is released, unchanged, and can be used for another reaction. This means that for each reaction, there does not need to be a 1:1 ratio between enzyme and substrate molecules. WebMechanism 2. Remember that in simple cases, where the slow step is the first step of the mechanism, the orders tell you what is taking part in the slow step. In this case, the reaction is first order with respect to both A and B, so one molecule of each must be taking part in the slow step. That means that mechanism 2 is possible.
