WebA gram of mouse tissue metabolizes more than 10 10 1 0 10 times faster than a gram of elephant tissue! Curiously enough, this is a very general relationship in nature. Among endotherms (animals that use body heat to maintain a constant internal temperature), the smaller the organism's mass, the higher its basal metabolic rate is likely to be. WebA reaction is spontaneous only if it's gibb's free energy change is negative . It is given that reaction is slower at a temperature below 11°C , so ∆S = positive and hence T∆S is …

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.

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.

WebEnzymes increase reaction rates by lowering the activation energy of a reaction. Enzymes increase reaction rates by interacting with the substrate molecules to facilitate the reaction, for example by contorting them to facilitate bond-breakage or orienting them to … WebThe step with larger activation energy is the slower step (as the fraction of collisions w/ enough energy to react will be smaller - activation energy requirement is higher) This derives from the Arrhenius equation: k = A * e^ (-Ea/RT) where A and R are constants, T = temp, and Ea = activation energy. As you can see, as Ea increases, k decreases.

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.

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.
