Question

Having trouble with this lab. This is the table. I am trying to figure out the final reaction rate. Can someone please do one and give me a step by step so I can do the rest.

Data Table 1: Varying the Concentration of 1.0 M HCL
---- C o n c e n t r a t i o n s ----
	# drops	# drops	# drops	Initial	Initial	Final	Final	Reaction Time (sec)			Reaction
Well #	HCl	Water	Na2S2O3	HCl	Na2S2O3	HCl	Na2S2O3	Trial 1	Trial 2	Average	Rate (sec-1)
1	12	0	8	1M	0.3M	0.6M	0.12M	23.46	30.03	26.7
2	6	6	8	0.5M	0.3M	0.15M	0.12M	41.15	31.22	36.2
3	4	8	8	0.33M	0.3M	0.066M	0.12M	46.12	37.12	41.6

Answer 1

Data Table 1: Varying the Concentration of 1.0 M HCL
---- C o n c e n t r a t i o n s ----
	#	#	# drops	Initial	Initial	Final	Final	Reaction Time (sec)			Reaction
	drops	drops
Well	HCl	Water	Na2S2O3	HCl (M)	Na2S2O3 (M)	HCl (M)	Na2S2O3 (M)	Trial 1	Trial 2	Average	Rate (sec-1) (with HCl )	Rate (sec-1) (with Na2SO4 )

1	12	0	8	1	0.3	0.6	0.12	23.46	30.03	26.7	0.007490637	0.00674157
2	6	6	8	0.5	0.3	0.15	0.12	41.15	31.22	36.2	0.004834254	0.00497238
3	4	8	8	0.33	0.3	0.066	0.12	46.12	37.12	41.6	0.003173077	0.00432692

Acording to the reaction, for HCl, the process is:

rate = (-1/2)*((final[]-initial[])/average time)

Number 2, is the estequimetrical coefitient for the reaction, so you can see both results and look at there are very similar.
