For the reaction `SnO_(2(s)) + 2H_(2(g)) hArr 2H_(2) O_((g)) + Sn_((d)) `. Calculate `K_(p)` at 900K, where the equilibrium steam hydrogen mixture was 45% `H_(2)` by volume.

A

1.49

B

1.22

C

0.67

D

6.7

Text Solution

Verified by Experts

The correct Answer is:
A
For an ideal gas mole = volume %
`K_(P)=(P^(2)H_(2)O)/(PH_(2)^(2))=((0.55)^(2))/((0.45)^(2))=1.49`
