At 550 K, the Kc for the following reaction is `10^(4) mol^(-1)L . X(g) + Y(g) rarr Z(g)` At equilibrium, it was observed that `[X] = 1/2[Y] = 1/2[Z]` . What is the value of `[Z]("in "mol^(-1)L)`at equilibrium ?

A

`2 xx 10^(-4)`

B

`10^(-4)`

C

`2 xx 10^(4)`

D

`10^(4)`

Text Solution

Verified by Experts

The correct Answer is:
A
`K_() = [Z]/([X][Y])`
given [Z]/[X] = 2
`10^(4) = 2/[Y] implies [Y] = 2 xx 10^(-4) implies [Z] = 2 xx 10^(-4)`
