Question

2. In experiment (C), speed of reaction increases if we use iron wire scrubber instead of iron nail.
Which factor do you observe that affects the rate of reaction ? Explain.​

Answer 1

The surface area of iron wire scrubber is very high compared to the surface area of iron nail of same mass.

More surface area means more site for the reaction to take place. This increase in area increases the speed of the reaction.

The factor responsible is surface area.
