Combustion of ocane follows the reaction:

2C8H18(l) + 25O2(g) --> 18H2O(g) + 16CO2(g)

When 12.3L of octane (d= 703g/L) are mixed with 4.0kg of oxygen gas in a 300L container at 298K. Assuming the temperature is kept constant throughout the entire process by mean of a coolant, calculate the highest pressure the system will reach. If the reaction vessel is certified to hold a max pressure of 12.0atm, will it be able to contain this reaction or will it crack?
