When concentrated sulfuric acid is poured onto sugar in a beaker and stirred, a vigorous exothermic reaction eventually occurs. a lot of steam is produced, and a black 'snake' consisting mainly of carbon rises out of the beaker. as this reaction takes a while to really get going, which of the actions listed below might speed up this process?

Missing question:
I. switching from granulated sugar to pow-dered sugar.
II. switching from powdered sugar to gran-ulated sugar.
III. warming up the sulfuric acid.
IV. putting the sulfuric acid container in an ice bath before use.
1. IV only
2. II only
3. III only
4. I and IV
5. I and III.
6. I only.
7. II and III
8. II and IV.
Answer is: 5. I and III.
If the surface area and temperature are increased, speed of reaction also increased.

The correct answer is b
