What's catalyst. The properties of catalyst

AlexFokin [52]

Answer:

Catalyst is a substance that increases the rate of a chemical reaction but is chemically unchanged at the end of the reaction.

properties of catalyst :

1. A catalyst increases the speed of a reaction, and it also improves the yield of the intended product.

2. A catalyst actually takes part in the reaction even though it itself is not consumed or used up in the course of the reaction.

3. A catalyst makes the reaction faster by providing an alternative pathway with a lower activation energy.

4. A catalyst is reaction-specific. It may not be effective in another reaction even if the two reactions are of similar type.

5. In a reversible reaction, a catalyst accelerates both the forward and the reverse reactions. So, the inclusion of a catalyst does not alter the equilibrium constant of a reversible reaction.

Complete Question

A marine biologist is preparing a deep-sea submersible for a dive. The sub stores breathing air under high pressure in a spherical air tank that measures 74.0 wide. The biologist estimates she will need 2600 L of air for the dive. Calculate the pressure to which this volume of air must be compressed in order to fit into the air tank. Write your answer in atmospheres. Round your answer to significant digits.

Answer:

The pressure required is $P_2= 12.2 \ atm$
