WebStudy Online IBDP Chemistry Prediction questions For SL Paper 1 Prepared By IB Physics Teachers And Subject Matter Experts ... The question is at the lower end of the “hard” category as students must know how to interpret a multi-step energy level diagram, identify both the RDS and the reaction enthalpy change and avoid confusing the ... WebThe reaction quotient aids in figuring out which direction a reaction is likely to proceed, given either the pressures or the concentrations of the reactants and the products. The Q value can be compared to the Equilibrium Constant, K , to determine the direction of the reaction that is taking place.

WebAt equilibrium, the value of the equilibrium constant is equal to the value of the reaction quotient. At equilibrium, (2.3.7) K e q = Q c = [ N 2 O 4] [ NO 2] 2 = 0.042 0.016 2 = 1.6 × 10 2. The equilibrium constant is 1.6 × 10 2. Note that dimensional analysis would suggest the unit for this K e q value should be M−1.

WebThe acid can be prepared by reacting the weak acid H 3 B O 3 (molar mass 61.83 g/mol) with HF according to the equation above. (a) To prepare a solution of B F 4 − (aq), HF (g) is bubbled into a solution containing 50.0 g of H 3 B O 3 in a 1 L reaction vessel. (i) Calculate the maximum number of moles of B F 4 − (aq) that can be produced. WebApr 13, 2024 · a level chemistry reaction preference question. It seems like the mark scheme is talking about reaction 2 being irreversible. This would mean that all the reactants would be used up to form as much product possible. In a reversible reaction like reaction 1 however, some of the reactants will not get used up as there will be equal rates of the ...
WebYou can calculate a value of ΔG as: ΔG = +178 - 293 (+0.1604) = +131 kJ mol -1 The value is positive and so the reaction isn't feasible. It cannot happen at this temperature. But suppose you heated it to 1000°C (1273 K). Recalculating gives: ΔG = +178 - 1273 (+0.1604) = … WebMar 30, 2024 · A simple example calculation will give you a feel for how to calculate Q for a reaction.
