Kc for the reaction SO2(g) + 1/2 O(2(g))...

`K_c` for the reaction `SO_2(g) + 1/2 O_(2(g)) to SO_(3(g)) " is " 61*7 " at " 60^@C`. What is its unit? Calculate `K_p` for the reaction and write its unit.`""^(**"**)`

Text Solution

Verified by Experts

The correct Answer is:
A, B
`Deltan= "moles of product" - "moles of reactant"`
`=1-(1+1/2)=-1/2`
`K_(p)=K_(c )(RT)^(Deltan)`
`K_(p)=61.7{0.0821xx(600xx273)}^(-1//2)=7.29`
`K_(p)=p_(SO_(3))/(p_(SO_(2)). P^(1//2)o_(2))=("atm")/("atm. atm"^(1//2))`
Unit of `K_(p)` is `"atm"^(-1//2)`
