Suppose you calibrated an apparatus by injecting 20.0 mL of air at 0.933 atm and 23.1.C into your apparatus containing 15. mL of water. The pressure in the apparatus is observed to change by 0.066 atm. For your apparatus, what is the value of the conversion factor that converts pressure into mole amounts, e.g. mole amount=conversion factor*average pressure change (in atm)?
Consider the exothermic reaction A(g) + B(g) C(g) + D(g). Would you expect the addition of heat to lead to the formation or consumption of A(g)? Why?
