How can you tell from a graph where the derivative is 0? Polonium is a radioactive isotope which decays by the loss of an alpha particle. What is the second product of this decay? How is the rate of reaction measured for an enzyme?
Calculate the rate constant in terms of hydrogen per cubic meter by dividing 180 kilograms by 0.3664. Therefore, the rate constant of this reaction is 491.3 kilograms of hydrogen per second per cubic meter. Each rate constant is valid because it is calculated using a different reactant as a b...
Heterogeneous catalysts control the rates of chemical reactions by changing the energy levels of bound intermediates relative to one another. However, the design flexibility in catalysis is limited by scaling relations: when a catalyst binds one adsorbat
Recent progress in understanding the Q-cycle mechanism of the bc1 complex is reviewed. The data strongly support a mechanism in which the Qo-site operates through a reaction in which the first electron transfer from ubiquinol to the oxidized iron–sulfur protein is the rate-determining step for ...
Our study focuses on five key chemical parameters believed to be of primary importance, more specifically, the rate of the reaction of NO2 with OH radicals, the newly identified HNO3-forming channel in the reaction of NO with HO2, the reactive uptake of N2O5 and HO2 by aerosols, and the...
DNA polymerases were named for their function of catalysing DNA replication, a process that is necessary for growth and propagation of life. DNA involving Watson–Crick base-pairing can be synthesized with high fidelity, the structural and mechanistic or
Since these key species are the ones whose relative energies most strongly influence the net reaction rate, they also identify the species whose energetics must be most accurately measured or calculated to achieve an accurate kinetic model for any reaction mechanism. Thus, it is very important to ...
Detractors respond with a score of 0 to 6. Your final NPS score can be calculated by subtracting the percentage of detractors from the percentage of promoters. CSAT is short for customer satisfaction, and is measured by asking customers a variation of this question: ‘How would you rate your...
The potential-pH diagrams of the Al–2.69Zn–2.87Mg–0.95Cu (at.%) alloy were calculated based on the CALculation of the PHAse Diagram method using Thermo-Calc software. An interaction system was set between 10−2 mol of Al-Zn-Mg-Cu single phase, 0.1 M NaCl in 1 kg of water...
On the basis of the calculated free-energy changes of the entire catalytic cycle (Fig. 4), the on-cycle resting state is the substrate-coordinated Rh(I) intermediate 4, and the rate- and regioselectivity-determining step is the concerted C−C bond cleavage and rhodium carbenoid formation via...
