Methane (ch4) is burned with 300 percent excess air in an adiabatic constant volume container. initially, air and methane are at 1 atm, 25oc. assuming complete combustion, determine the final pressure and temperature of the combustion products.

When 225mg of anthracene, c14h10(s), was burned in a bomb calorimeter the temperature rose by 1.75k. calculate the calorimeter constant. by how much will the temperature rise when 125mg of phenol, c6h5oh(s), is burned in the calorimeter under the same conditions? (δch< (c14h10,s)=–7061 kj mol−1.)
