Consider the subsequent reaction in a closed reaction flask. If 1.50 atm of gas A is permissible to react with 0.500 atm of gas B and the reaction goes to finishing point at constant temperature and volume, explain what is the total pressure in the reaction flask at the end of the reaction? Define what are the partial pressures of the gases in the flask?
6A(g) + 2B(g) 2A3B(g)
A. (0.250 atm of A3B produced) + (0.500 atm of A remaining) = 0.750 atm total pressureB. (0.500 atm of A3B produced) + (1.00 atm of A remaining) = 1.50 atm total pressureC. 0.500 atm of A3B is produced, and since no other gases remain, 0.500 atm is the total pressureD. (0.500 atm of A3B produced) + (0.500 atm of A remaining) = 1.00 atm total pressure
Use average bond energies to estimate enthalpy changes for C(s) + CO2(g) -----> 2CO(g) i got -221 kj/mol, but it was the wrong answer though.
The normal boiling point of bromine is 58.8°C. Given that the vapor pressure of methanol is 75.0 torr at 2.5°C, calculate the molar enthalpy of vaporization of bromine.
