Question

For every 10°c rise in temperature, the rate of chemical reaction doubles. When the temperature is increased from 30°c to 70°c, the rate of reaction increases __________ times

Answer 1

HEY ..........

⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕

FOR EVERY 10°C ......

TEMPERATURE DOUBLES.....

⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕

GIVEN TEMP IS 30-70°©

THE RISE IN THE TEMP IS .....

70-30 = 40°C

MEANS .....

⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕

LET THE RATE OF REACTION WAS X AT THE TEMP OF 30°c....

⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕

AT 40°© IT WILL BE

2*X

2X

⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕

AT 50°©

IT WILL BE

2X *2

4X....

⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕

AT 60°© THE RATE WILL BE ....

4X *2

8X

⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕

AT 70°©

TEMP WILL BE.....

8X*2

16X.....

⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕

SO THE RATE OF REACTION INCREASES " 16 " TIMES ......
