Butane gas burns in air according to the following reaction.
`2C_(4)H_(10) +13O_(2) rarr 10 H_(2)O +8 CO_(2)`.
Suppose the initial and final temperature are equal and high enough so that all reactants and products act as perfect gases. Two moles of butane ar mixed with `13` moles of oxygen and then completely reacted. Find the final pressure (if the volume remains unchanged and the pressure before reaction is `P_(0))`?
