14. For the following first-order reaction X → Y, the number of X molecules are placed in three same vessels at 100°C (i= 8 molecules, ii = 6 molecules, iii = 12 molecules) (a) compare rates of the reaction in these three vessels? (b) if the volume of each vessels were doubled, how would the relative rates be changed? (c) Explain the comparative t1/2 of the reactions in (i) to (iii)? 15. Variation of the rate constant with temperature for the first-order reaction 2N2O5(g)→2N2049) + Ozg) is given in the following table. Determine graphically the activation cnergy for the reaction. k (s ) 1.74 x 105 6.61 x 105 2.51 x 104 T (K) 295 305 315 325 7.59 x 104 335 2.40 x 10
