Question

Can someone please help me finish the tables and calculations.

Thanks in advance

Answer 1

p= 2.367

Table 4

Rate constants:

1) k= 4.55 × 10^9

2) k= 4.759 × 10^9

3) k= 4.472 × 10^9

4) k= 4.53 × 10^9

k average = 4.57775 ×10^9

Table 5:

Temp °C	average time (seconds)	temp K	relative rate
25	141.2	298	7.08
5.3	344	278.9	2.9
18.5	170	291.5	5.88
22	85	295	11.764
37.33	41	310.33	24.324

  

Table 6:

Reaction temp °C	T K	1/ T	k	ln k
5.3	278.3	.00359
18.5	291.5	.00343
25	298	.00335
29	302	.00331
37	310	.00322

The values of k are known only for the above 4 temperatures in in table 1.

For further calculations of k at different temperatures other than those mentioned in table 1 one need more data for k calculation at 5.3 18.5 29 and 37 °C. I hope you get my point and for furyher queries feel free to contact and then I can help you further with the calculations.

Thank you
