题目 The equilibrium constant (Keq) is fixed and characteristic for any given chemical reaction at a specified temperature. It defines the composition of the final equilibrium mixture, regardless of the starting amounts of reactants and products. A.正确B.错误 相关知识点: 试题来源: 解析 A ...
The overall contribution of the negatively charged surface of halophilic proteins to fold stabilization by KCl can be computed as the sum of the differences between fold stabilizing and destabilizing effects of each carboxyl group:(Equation 2)mKClelec=∑(mKClelec,F(i)−mKClelec,U(i)). Figur...
If the following equation is expanded into an evacuated flask, in which direction will the equilibrium shift - left or right? CO2(g) + 2NH3(g) gives H2NCONH2(s) + H2O(g). In which direction will the point of equilibrium shift ...
can be calculated using the equilibrium constant expression which is expressed by dividing the equilibrium molar concentrations of the products with the equilibrium molar concentrations of the reactants. Each molar concentration must be raised to the power ...
The number of amino acids in each sample to experience a change in helicity from −10 to 37 °C was estimated using a previously developed helix–coil transition model, which gives the change in fraction of helicity (ΔfHelix) by Equation 1 (19, 49, 50), (Eq. 1)Δfhelix=fhelix...
The new equation yields a significantly improved agreement on the average helix-block length with the original Zimm-Bragg theory for both medium and long chain lengths in the entire temperature range. Nevertheless, even the original Zimm-Bragg theory does not provide an accurate description of helix...
It is also important to consider the Kb value of NH3 in this calculation, as it will affect the equilibrium and ultimately the end point pH. By plugging in the appropriate values into the Henderson-Hasselbalch equation, we can solve for the end point pH. In summary, to solve this problem...

Furthermore, the chemical reaction number 3 in Table 8 (NO oxidation reaction) has a parameter called “keq” that is the equilibrium term depending only on the catalyst temperature and given by Equation (12): keq=exp{0.5·[−9.25+6848T+0.28·T1000−0.022·(T1000)2−0.41·ln(T1000...
