The equilibrium constant of H2 combustion at 1500K surpass that of N2 combustion at 2200K by at least 2 orders of magnitude.
Without first writing a full molecular or ionic equation, write the net ionic equations for any precipitation reactions that occur when aqueous solutions of the following compounds are mixed.
A sample of S8 (g) is placed in a container at 1325 K at an initial pressure of 1.00 atm, where it decomposes to S2 (g) by the reaction, S8 (g) 4S2 (g), At equilibrium, the partial pressure of S8 (g) is 0.25 atm. The Kp at 1325K is
An unknown Chromium solution was mixed with aliquots of a standard solution of Chromium for atomic absorption spectroscopy. The standard solution contained 1000 ppm of Chromium (this is [s]i)
The final temperature of the mixture is 27.0 degrees celsius. What is the heat capacity of the unknown substance?
Find the temperature at which Kp = 4.00 for the reaction N2O4(g) 2NO2(g). [Given: at 25°C, for NO2(g), ?H°f = 33.85 kJ/mol, S° = 240.46 J/mol·K; for N2O4(g), ?H°f = 9.66 kJ/mol, S° = 304.3 J/mol·K; assume that ?H° and ?S° are independent of temp..
