30 -----> 40=2. times.
40 -----> 50=4 times.
50 -----> 60= 8 times.
60 -----> 70=16 times.
40 -----> 50=4 times.
50 -----> 60= 8 times.
60 -----> 70=16 times.

K = FACTOR^(t/range).
K = 2^(40/10).
K = 2^4.
K = 16.
K = 2^(40/10).
K = 2^4.
K = 16.

Increase of temp = 40°c = 4 * 10°c.
So , K=2^4 = 16.
So , K=2^4 = 16.

For every rise in temperature by 10°C the reaction doubles right?
So, from 30 to 40 the reaction is like 2 and from 40 to 50 is double of 2 which is 4.
Then from 50 to 60 is a double of 4 which is 8 and lastly from 60 to 70 is double of 8 which is 16. Or for 40°C rise in temperature is like 4 times 10°C.
If for rise in temperature, the reaction doubles, then at 40°C rise, 4*4=16.

From 10---->20=1 chemical reaction takes place
20---->30=2
30----->40=3
40---->50=4
50---->60=5
60---->70=6
first 10----->30=2 reaction takes place total chemical reactions 8
chemical reactions are doubled 8x2=16
20---->30=2
30----->40=3
40---->50=4
50---->60=5
60---->70=6
first 10----->30=2 reaction takes place total chemical reactions 8
chemical reactions are doubled 8x2=16

@Surendra is right only.
for every 10C rise, rate of reaction doubles.
30-40 = 10 C (1)
40-50 = 10 C (2)
50-60 = 10 C (3)
60-70 = 10 C (4)
For every 10 C rise rate becomes doubles so 2^4 = 16.
