Calculate ?Grxn at 298 K under the conditions shown below for the following reaction. 3O2(g)--> 2O2(g) ?G°=326 kJ P(O2) = 0.41 atm, P(O3) = 5.2 atm
The falling down of a piece of chalk (when the hand holding it is taken off) is an energy-controlled process, because there is no change in its entropy in the process.
The acid-catalyzed addition of alcohols to alkenes occurs via a mechanism analogous to acid-catalyzed alkene hydration. The reaction occurs in 3 steps
Calculate the partial pressure (in atm) of HBr at equilibrium when 5.00 atm of CH3Br and 5.00 atm of H2O react at 1000 K according to the following chemical equation
An attempt at synthesizing a certain optically active compound resulted in a mixture of its enantiomers. The mixture had an observed specific rotation of 11.0°. If it is known that the specific rotation of the R enantiomer is -31.0°, determine the..
