The reaction describing the formation of ozone from oxygen is shown below. 3 O2(g) <--> 2 O3(g) Calculate Grxn at 288 K for this reaction in a flask where [O2] = 3.419 x 10-2 M and [O3] = 5.783 x 10-4 M. Assume G° = 326 kJ. Use molarity to construct the reaction quo...

Chemistry
For the reaction: 2 NO(g) + 1 O2(g) <--> 2 NO2(g) Calculate K, the equilibrium constant, from thermodynamic data at 281 K. (Hint #1: Assume that S and H do not change with temperature.) (Hint #2: Work in J/mol)

Chemistry
Find delta G knot for the following reaction: 2Ch3OH(l) + 3O2(g) --> 2CO2(g) + 4H2O(g)

Chemistry
For the reaction below 2 CH3OH(l) + 3 O2(g) 2 CO2(g) + 4 H2O(g) calculate Srxn at 298 K. (Hint: Use a table of thermodynamic data commonly found at the back of chemistry textbooks.)

Thank you Dr. Bob.

Chemistry
A researcher is studying the decomposition of A as shown by the general reaction below: 2 A(g) 4 B(g) + 2 C(g) Initially, the scientist fills an evacuated 1.772 L flask with 3.710 x 10-1 moles of species A. Upon equilibrium, it is determined that the concentration of A is 4.60...
