08 Oct 2015 Temperature Increase

On increasing the temperature by 30 degree centigrade, rate of a chemical reaction becomes 15.625 times the initial rate. If every 10 degree centigrade increment in temperature makes the similar multiple change (x), then x is equal to

OPtion

1) 0.5
2) 3.5
3) 4.5
4) 1.5
5) 2.5
6) 5.2083
7) 2.705
8) 2.505
9) 5.05
10) 1.25

Solution

30 degree centigrade means three laps of 10 degree centigrade
According to the given condition
(initial rate) . x . x . x = 15.625 (initial rate) Or x3 = 15.625
Or x = 2.5

Option 5)

30 degree centigrade = three laps of 10 degree centigrade
Let Initial rate = y

as per the given condition

y . x . x . x= 15.625 . y
x^3 = 15.625
so, x = 2.5

(initial rate).x.x.x=15.625
x^3=15.625
x=2.5
because centigrade increment in term of 10

from question,
If every 10 degree centigrade increment in temperature makes the similar multiple change (x).

On increasing the temperature by 30 degree centigrade, rate of a chemical reaction becomes 15.625 times the initial rate, then
10+10+10=30 means there is 3 slaps
if temp. increased by 10 degree centigrade rate of reaction become x time initial rate
again temp increased by 10 degree centigrade rate of reaction become square of x. at 20 degree centigrade
similarly, at 30 degree centigrade the rate of reaction become cube of x.
cube of x = 15.625
so, x = 2.5
