Q1. The rate of a reaction get doubles when the temperature changes from 7℃ to 17℃. By what factor will it change for the temperature change from 17℃ to 27℃?
  •  1.81
  •  1.71
  •  1.76
  •  1.91

Q2.In Arrhenius plot intercept is equal to
  •  -E_a/R
  •  ln⁡A
  •  ln⁡k
  •  log_10⁡a
Q3.  The reaction L→M is started with 10.0 g of L. After 30 and 90 min, 5.0 g and 1.25 g of L respectively are left. The order of the reaction is
  •   2
  •  3
  •  0
  •  1
10 g→5 g→2.5 g→1.25 g takes 30 min in each step, ie,t^(1/2) is independent of 'a' hence, it is a first order reaction

Q4. A first order reaction is 50% complete in 30 min at 27℃ and in 10 min at 47℃. The energy of activation of the reaction is
  •  52.8 kJ
  •  23.6 kJ
  •  29.5 kJ
  •  43.8 kJ

Q5.Select the intermediate in the following reaction mechanism: O_3 (g)⇌O_2 (g)+O(g) O(g)+O_3 (g)⟶2O_2 (g)
  •  O(g)
  •  O_2 (g)
  •  O_3 (g)
  •  None of these
 The intermediates species is one which is formed and used up during the course of reaction.

Q6. If a certain reaction is first order with respect to A, second order with respect to B and zero order with respect to C then what is the order of reaction?
  •  Zero
  •  Third
  • Second
  •  First
Rate law dx/dt=k[A]^1 [B]^2 [C]^0=k[A]^1 [B]^2 Hence, order of reaction =1+2=3

Q7.Ethylene is produced by cyclobutane as: C_4 H_8 □(→┴∆ ) 2C_2 H_4 The rate constant is 2.48×〖10〗^(-4) sec^(-1). In what time will the molar ratio of the ethylene to cyclobutane in reaction mixture attain the value 1?
  •  20 minute
  •  25 minute
  •  27.25 minute
  •  28.25 minute

Q8.For the reaction system, 2NO(g)+O_2 (g)→2NO_2 (g) Volume is suddenly reduced to half its value by increasing the pressure on it. If the reaction is of first order with respect to O_2 and second order with respect to NO; the rate of reaction will
  •  Diminish to one –fourth of its initial value
  •  Increase to eight time of its initial value
  •  Increase to four time of its initial value
  •  Diminish to one –eighth of its initial value


Q9.The rate constant for the first order reaction is 60 s^(-1). How much time will it take to reduce the concentration of the reaction to 1/16 M value ?
  •  4.6×〖10〗^(-4) s
  •  4.6×〖10〗^2 s
  •  4.6×〖10〗^4 s
  •  4.6×〖10〗^(-2) s

Q10. For a reaction 1/2 A→2B, rate of disappearance of ‘A’ is related to the rate of appearance of B by the expression
  •  -d[A]/dt=1/2(d[B])/dt
  •  -d[A]/dt=1/4(d[B])/dt
  •  -d[A]/dt=(d[B])/dt
  • -d[A]/dt=4(d[B])/dt
