When the liquid is burned, the reaction involved is 2 C5H12O(ℓ) + 15 O2(g)10 CO2(g) + 12 H2O(g) The standard enthalpy of formation of liquid 1-pentanol at 25 °C is -351.6 kJ mol-1; other relevant enthalpy of formation values in kJ mol-1 are: C5H12O(g) = -294.6 ; CO2(g) = -393.5 ; H2O(g) = -241.8 (a) Calculate the enthalpy change in the burning of 5.000 mol...
Why must we use a novel approach when we solve for equilibrium concentrations in formation reactions?...
Why must we use a novel approach when we solve for equilibrium concentrations in formation reactions? None of these Large Kfvalues ensure that nearly all of the limiting reactant is consumed Formation reactions never really reach equilibrium, and instead stop when the limiting reactant is completely consumed Products of formation reactions are unstable and participate in many side-reactions Formation reactions tend to be exothermic, which normal ICE tables don't account for Oxidation numbers always change in formation reactions
