WebTo solve this problem, we assume each peanut, with an average mass of 0.73 g, is 49% peanut oil and 21% starch; the remainder is noncombustible We further assume peanut oil is palmitic acid, C16H32O2, with an enthalpy of formation of 848.4 kJ/mol. Starch is a long chain of C6H10O5 units, each unit having an enthalpy of formation of 960 kJ. WebFeb 19, 2016 · Your precision is limited to 3 significant figures by the 298 K term (it's really 298.15 K). So the best value you can get for RTlnQ is 33 000 J = 33.0 × 10³ J. Δ G = -33.0×10³ J + 33.0×10³ J = 0.0 × 10³ J. A value of 4.27 J is the same as 0.0 × 10³ J within the limits …

WebJan 10, 2024 · Qc and Kc are calculate the same way, but Qc is used to determine which direction a reaction will proceed, while Kc is the equilibrium constant (the ratio of the concentrations of products and reactants when the reaction is at equilibrium). So, Qc could be = to Kc, but it may not be.
