Question

genral characterstics of catalysts.???

Answer 1

Answer:

Hey mate here is your answer...

________________________________

● General characteristics of Catalyst..

> A catalyst remains unchanged in mass and chemical composition but can change their physical state.

> Only a very small amount of Catalyst in sufficient to catalyse a reaction

> A catalyst does not initiate a reaction

> When a catalyst is a solid, it is usually more efficient when used in finely divided form.

> Generally does not change the equilibrium state of a reversible reactiom but helps to achieve the equilibrium state or position of euqlibrium in lesser time.

> The catalysts is generally specific in nature.

> Change rate constant of reactio.

Hope it helps u!(:

Answer 2

Explanation:

Molecular mass=2*vapour density

Molecular mass=2*vapour density =2*11.2

Molecular mass=2*vapour density =2*11.2=22.4 g

Molecular mass=2*vapour density =2*11.2=22.4 gAt NTP,

Molecular mass=2*vapour density =2*11.2=22.4 gAt NTP,volume occupied by 22.4 g of gas= 22.4 l

Molecular mass=2*vapour density =2*11.2=22.4 gAt NTP,volume occupied by 22.4 g of gas= 22.4 lvolume of 11.2g gas = 22.4/22.4*11.2

Molecular mass=2*vapour density =2*11.2=22.4 gAt NTP,volume occupied by 22.4 g of gas= 22.4 lvolume of 11.2g gas = 22.4/22.4*11.2= 11.2 l
