It is often said the resonance stability of phenol makes it a stronger acid than that of aliphatic alcohols such as ethanol (pK a = 10 vs. 16–18). However, a significant contribution is the greater electronegativity of the sp 2 alpha carbon in phenol compared to the sp 3 alpha carbon in aliphatic alcohols. [7]
The relative activity of a species i, denoted a i, is defined [4] [5] as: = where μ i is the (molar) chemical potential of the species i under the conditions of interest, μ o i is the (molar) chemical potential of that species under some defined set of standard conditions, R is the gas constant, T is the thermodynamic temperature and e is the exponential constant.
How do the spin–orbit coupling, other relativistic corrections, and inter-electron effects modify the chemistry of the trans-actinides? [1] [2] Is it possible to create a practically-useful lithium–air battery? [3]
where: k 1 is the rate coefficient for the reaction that consumes A and B; k −1 is the rate coefficient for the backwards reaction, which consumes P and Q and produces A and B. The constants k 1 and k −1 are related to the equilibrium coefficient for the reaction (K) by the following relationship (set v=0 in balance):
Clearly, E = 3 means there are three irreps and a C 2 representation sum of 1 means there must be two A and one B irreps so the only combination that adds up to the characters derived is 2A 1 + B 1 Robert Mulliken was the first to publish character tables in English (1933), and E. Bright Wilson used them in 1934 to predict the symmetry of ...

When silver nitrate (AgNO 3) is added to a solution of potassium chloride (KCl) the precipitation of a white solid (AgCl) is observed. [5] [6] AgNO 3 + KCl → AgCl↓ + KNO 3. The ionic equation allows to write this reaction by detailing the dissociated ions present in aqueous solution. Ag + + NO − 3 + K + + Cl − → AgCl↓ + K + + NO − 3
