The effect of temperature on rate of reaction is just one of the things that can affect how a reaction proceeds, that is, how quickly whatever reactants are present become transformed into products. Of course, many of these factors are active at all times and can have competing influences o...
C. There is a positive relationship between temperature and the rate of this chemical reaction. D. Temperature is the only factor affecting the rate of chemical reactions. 相关知识点: 试题来源: 解析 C。A 选项说温度对化学反应没有影响,与题目表述矛盾。B 选项说温度越高,所有化学反应都越快,过于...

In differential thermal analysis, the temperature at which the maximum deflection is observed varies with heating rate for certain types of reactions. An expression can be derived relating this variation with the kinetics of the reaction. By making a number of differential thermal patterns at differen...
Figure 5.6.Diagram indicating how the rate of the graphite-molecular oxygen reaction changes with increasing reaction temperature, 1300–2300 K (Lewis (1970)). This would suggest that changes introduced to the structure of an isotropicporous carbonduring a thermalactivation processwill remain and will...

The influences of reaction temperature, pressure and H2/N2 ratio on the performance of the catalyst were investigated in detail. The relative concentration of H2 and N2 in the reactant stream highly influenced the catalytic activity. The remarkably higher rate of NH3 synthesis was observed for the...
The ion transport is also a thermally activated process, just like the rate of a chemical reaction. [7]σ=σoexp(−EakT) where σo is the pre-exponential factor, Ea is in J mol−1 or eV, k is the Boltzman constant, and T is temperature in K. Taking the logarithm (log or ...
5. What can be inferred from the comparison of terrestrial animals to marine animals in the last sentence of paragraph 4? A. An animal's size is not the only factor affecting its metabolic rate. B. An animal's size determines what mechanism can be successfully used to prevent heat loss....
