Question

Heats of atomization of ozone and oxygen are 25 units and 30 units respectively. The heat of ozonisation of one mole of oxygen is5 x

What is the x value

Answer 1

Answer:

A gas mixture of volumetric composition 45% CO,

50% CO, and 5% N, was passed over ZnO at 1380 K,

so that Zn vapours was produced according to the

reaction:

ZnO + CO ZnO + CO2(g)

Under steady condition, the rate of input gas flow at

STP is 0.224 dmmin. The rate of loss of mass of

ZnO is 5 x 10-4 mol min, P=770 torr. Find Kpat

1380 K assuming ideal gas behaviour.

x = 8.
