- Show by calculation, using Appendix 1, whether dissolving lead(II) chloride PbCl2(s)Pb2+(aq)+2Cl(aq) is spontaneous at 25C (a) when [ Pb2+ ]=1.0M;[ Cl ]=2.0M. (b) when [ Pb2+ ]=1.0105M;[ Cl ]=2.0105M.arrow_forwardEstimate the temperature range over which each of the following reactions is spontaneous. (a) 2Al(s)+3Cl2(g)2AlCl3(s) (b) 2NOCl(g)2NO(g)+Cl2(g) (c) 4NO(g)+6H2O(g)4NH3(g)+5O2(g) (d) 2PH3(g)3H2(g)+2P(g)arrow_forwardWhat is a spontaneous reaction?arrow_forward
- Calculate E°, G°, and K at 25°C for the reaction 3Mn2+(aq)+2MnO4(aq)+2H2O5MnO2(s)+4H+(aq)arrow_forwardIf you calculate a value for G for a reaction using the values of Gf in Appendix 4 and get a negative number, is it correct to say that the reaction is always spontaneous? Why or why not? Free energy changes also depend on concentration. For gases, how is G related to the pressure of the gas? What are standard pressures for gases and standard concentrations for solutes? How do you calculate G for a reaction at nonstandard conditions? The equation to determine G at nonstandard conditions has Q in it: What is Q? A reaction is spontaneous as long as G is negative; that is, reactions always proceed as long as the products have a lower free energy than the reactants. What is so special about equilibrium? Why dont reactions move away from equilibrium?arrow_forwardIs the following reaction spontaneous as written? Explain. Do whatever calculation is needed to answer the question. CH4(g)+N2(g)HCN(g)+NH3(g)arrow_forward
- Thermite reactions have been used for welding metal parts such as railway rails and in metal refining. One such thermite reaction is Fe2O3(s)+2Al(s)Al2O3(s)+2Fe(s). Is the reaction spontaneous at room temperature under standard conditions? During the reaction, the surroundings absorb 851.8 kJ/mol of heat.arrow_forwardCalculate \Delta G (in kJ) at 298 K for some solid ZnF2, 0.073 M Zn2+ and 0.033 M F-(aq). Which direction is the reaction spontaneous? \Delta Go =-713.15 kJ/molarrow_forwardIs the reaction MgO (s) + C (s) → Mg (s) + CO (g) spontaneous at 1500 ºC?arrow_forward
- What is the difference between Δ G° and ΔG? Under whatcircumstances does ΔG=Δ G°?arrow_forward(11111) Which of the following statements determine a reaction to be spontaneous? The ∆Hrxn is positive. The ∆Suniv is positive. The ∆G0 is positive. The ∆Srxn is positive.arrow_forwardChemistry Please construct the microstate table for Fe(OH)3 and how to calculate it. (must show the table) Please don't give me answers that are already on Chegg cause it's not what I need, thanks.arrow_forward
