Question

20) Which statement is true concerning the stand A) The standard state for N2() is the pure gas at 1 atm. B) The standard state for N2() is the pu at a concentration of 1 mol/L. tre concerning the standard states of N2(x) and C12H22011(aq)? te for N2(8) is the pure gas at 1 atm and for C12H22011(aq) is the pure solid 20) — ndard state for N2() is the pure gas at 1 mol/L and for C12H22011(aq) is the solution ) The standard state for N2() is the pure gas at 1 mol/L and for C12H22011(aq) is the pure solid at 1 atm. D) The standard state for N2(8) is the pure gas at 1 atm and for C12H22011(ag) is the solution at a concentration of 1 mol/L. SHORT ANSWER. Write the word or phrase that best completes each statement or answers the question. 21) The reaction 2 H20(8) + CO2(8) - CH4(8) +2 CO26) is nonspontaneous at 25°C. The 21) addition of a catalyst will (decrease, increase, not change) the rate of reaction and (decrease, increase, not change) the spontaneity of the reaction. MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question. The figure below represents the spontaneous reaction of H2 (shaded spheres) with O2 (unshaded spheres) to produce gaseous H2O. 88 008 22) How will the spontaneity of this reaction vary with temperature? This reaction is A) nonspontaneous at all temperatures. B) spontaneous at all temperatures. C) nonspontaneous at high temperatures and spontaneous at low temperatures. D) spontaneous at high temperatures and nonspontaneous at low temperatures.

Answer 1

20th answer is D

standard state of Ny (9) means lato pressure (standard State), In generally 'No' standard state is gas. - Standard state of Me (9) means, pure gas at latma standard state of Catha, (aq), means aqueous means at concentration of solution. so a mollit. pure solution - Answer: D + Pure gas of at 1 mol/L. My at tatm and solution I are gas liquid is gas hatm pressure. solution, concentration = IMOL 1M
