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

30 -----> 40=2.

40 -----> 40=2*2.

50 -----> 60=2*2*2.

60 -----> 70=2*2*2*2 = 16 times.

@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.

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

K = 2^n,
K = 2^(40/10),
K = 2^4,
K = 16.

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

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