Refer to the Introduction section where the identity of the rate- determining reaction was discussed. Suppose that the rate constant for reaction (1a) increases by 2% for each increase of 1 oC, and the rate constant for reaction (1a) increases by 20% for each increase of 1 oC. What would be the percent decrease in the observed elapsed time when the temperature increases by 1 oC? a. 2%.b. 20%.c. 2+20= 22%.d. 0.02 X 20 = 0.4%.

beta decay is the answer

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
