Question

Question 1 (5 points) Cyclohexane, C6H12, undergoes a molecular rearrangement in the presence of a catalyst to form methylcyclopentane, CH3C5H9, according to the equation: C6H12 - CH3C5H9 If Kc = 0.143 at 25°C for this reaction, find the equilibrium concentrations of C6H12 and CH3C5H9 if the initial concentrations are 0.200 M and 0.075 M, respectively. [C6H12] = 0.241 M, [CH3C5H9] = 0.034 M (C6H12] = 0.082 M, [CH3C5H9] = 0.062 M [C6H12] = 0.159 M, [CH3C5H9] = 0.116 M [C6H12] = 0.253 M, (CH3C5H9] = 0.022 M [C6H12] = 0.041 M, (CH3C5H9] = 0.041 M

Answer 1

Ans 0200my 0.075M Using Cohia initial concentration CH3 Cg Hq initial concentration ICE table Cotia ² CH3 Cg Hq O:200M 0.075 M I С E - +7 0.2 00-X 0.075+ x At equillibrium , equilibriom constant is given by Ke [CH3 Cs Hq [Cho Value Кс . 0.143 of at as°c (at given) 0.143 = o.075 tx cuss (By multiplying) 0200-X 00286 0.1434 0.075 + x O 0286 -0.075 0.143x ta -0.0464 1.143x 20 00464 1.143 7 = -0.0406

Therefore, concentration of GHz at equilibrium [C6 He [6 His [Coho] 0.200 x 0.200-(-0.0406) 0.241M of at equilliberium, D 0.075 ta and Concentration CH₃ G Hq [CH3 Cg Ha] = 0.075+ (-0.0406) ECHz Cs Ha] = 0.0347 Thus (6 Hp] = 0·241M and [CH3 Cg Ha] = 0·034M
