Endothermic, Exothermic & Rates Of Reaction

Releasing heat

Absorbing heat

Producing heat

Yes

No

Option 4

A chemical that changes while speeding up the rate of reaction

A chemical to slow down the rate of reaction

A chemical that speeds up the rate of a reaction without being changed in the process.

A chemical that reacts to form a new product while speeding up the rate of reaction

Because the ocean going ship is always in the sea water

Because the sea water speeds up the reaction of the iron rusting

Because the iron's quality is bad

Because increasing the temperature makes the particles become bigger and so it can touch other particles more quickly and react.

Because increasing temperature gives particles more energy. When particles moves faster, it increases the chances of collision and collisions are harder.

Because increasing the temperature causes the particles to rise quickly.

True

False

Because more particles are exposed to collision with other particles causing a faster rate of reaction.

Because the particles can move about more freely to collide causing a faster reaction.

Because less particles are exposed to collision with other particles causing a faster rate of reaction.
