9.The combustion of 5.43 g C5H8O2 at 34.2 ̊C and in a container of 4.32 L, with a pressure of 5.64 atm of O2 present, what is the total pressure of gas in the container after the reaction? Assume the temperature stays constant.

Solutions

Expert Solution

In the question, we are assuming first that at the given temperature water produced is in liquid state. And accordingly total pressure of gases after reaction is complete , is calculated.

Again if water is also present as gas, than total gaseous moles after reaction will increase, and total pressure is calculated for this case also.

Also, The partial pressure of O2 alone after reaction is complete in either case will be =
