To determine the Gibbs free energy change (ΔG) for a reaction at 25°C, you would typically need the standard Gibbs free energies of formation (ΔG°f) for the reactants and products involved in the reaction. ΔG can be calculated using the formula ΔG = ΣΔG°f(products) - ΣΔG°f(reactants). If you provide the specific reaction and the necessary thermodynamic data, I can help you calculate ΔG.
To convert kg to dg multiply by 10000. 1 g = 10 dg 1 kg = 1000 g = 1000 x 10 dg = 10000 dg
To convert decigrams (dg) to hectograms (hg), you can use the conversion factor where 1 hg equals 10 dg. Therefore, to convert 1500 dg to hg, you divide by 10. So, 1500 dg is equal to 150 hg.
CaCO3 -> CaO + CO2
The abbreviation for decigram - a unit of mass equal to 0.1 grams - is dg.
The products of neutralization reaction are water and a salt.
A pair of reactants that will result in a spontaneous reaction at 25C is one where the Gibbs free energy change (G) is negative. This means that the products have lower energy than the reactants, driving the reaction forward.
You would need 5.7 grams of mercury II oxide to produce 1.56 L of oxygen gas according to the following reaction at those conditions.
25c = 298.15k
DeltaG = DeltaH - TDeltaS dG = -54.32 kJ/mol - (54'32+273)K(-354.2J/molK) NB Thevtemperature is quoted in Kelvin(K) and the Entropy must be converted to kJ by dividing by '1000'/ Hence dG = - 54.32kJ/mol - (327.32K)(-0.3542 kJ/molK) NB The 'K' cancels out. Then maker the multiplication dG = -54/32 kJ/mol - - 115.94 kJ/mol Note the double minus; it becomes plus(+). Hence dG = -54.32kj/mol + 115.94 kJ/mol dG = (+)61.61 kJ/mol Since dG is positive, the reaction is NOT thermodynamically feasible.
