Question

how do i do these two questions?

Assume that the reaction: CO(g) + H2O(g) = CO2(g) + H2(g) occurs in an ideal mixture of ideal gases. At 700.K, K=3.61. At this temperature, AG° equals: Select one: a.-7.47 kJ b. Oku 0 C. -3.74 kJ o d. 7.47 kJ -200 kJ. For the following reaction producing 1 mol of oxygen gas at a particular temperature, AH NO(g) +O3(g) → NO2(g) + O2(g) The activation energy is 11 kJ/mol. What is the activation energy for the reverse reaction? Select one: a.'11 kJ/mol b. 200 kJ/mol c. 188 kJ/mol d.211 kJ/mol The overall reaction A - proceeds through several steps as delineated in the reaction energy diagram b listed below is consistent with this reaction energy diagram?

Answer 1

Dear student,

Aus. CO(g) + H₂O (9) - CO₂ (9) + H219) ginen, Kp 3.61 T = 700 K , As we know that, relationship between 8Go 8 kp is geven as NO oGo = –RT M Kp. where , R=8,314 I/ mol-k = gas constant T = temperature in Keluin Kp = equlibrium constant. AGO - Standard Gibbs free energy & ab = – 8.314 I x Fook & lu (3.619 - molt AGO = -5819.8* 1.284 Tomo Go &– 74 72.6232 5 / omol AG ––7.47 kJ/mol so IKI = 1000 T} .

Hence option A is correct answer.

NO₂ (g) + O2 19). NO (9) + Opl9) - ginen, OH = -20okJ. Ea) forward = 11 kJ/mol It is given that for production of tomoz . I mole of Oz (9) OH = -200 IT o. Sheron =-200 kJ lonol. for abone, reaction. & Shaxn = (a) forward - Ea) backward & Ea) backward = Ea) for world – 8 Haxen = 11 kJ/mol - (- 200 kJ/mal) È 11 K5 Imol + 2001e5lmol = 211 kg lool

Hence option D is correct answer.
