The reaction between iron (III) oxide and aluminum, to produce aluminum oxide and iron, has a heat of reaction (ΔH) equal to -851.5 kJ/mole. How much energy is released if 0.56 moles of aluminum are consumed?
Derive the relationship that the effective rate constant of the reaction K is the same as (d[P]/dT)/([A][B]) takes the form k= k2 exp(-deltaG/RT) Where deltaG(these deltaG are with double dagger )is the standard free energy difference between the ..
