Hydrogen Peroxide

State whether...

Question

State whether the given statement is true or false:

The mixture of hydrazine and hydrogen peroxide with a copper (II) catalyst is used as a rocket propellant.

Open in App

Solution

In the presence of Cu(II) catalyst, hydrogen peroxide oxidises hydrazine to nitrogen. The reaction is highly exothermic and is accompanied by large increase in volume. Therefore, the mixture provides an upward thrust and is used as a rocket fuel.

$N H_{2} - N H_{2}$ + $2 H_{2} O_{2}$ $c u I I \to$ $N_{2}$ + $4 H_{2} O$ + $H e a t$
