For a hypothetical reaction: `A(g) +B(g) hArr C(g) +D(g)` a graph between log `K_(eq)` and `T^(-)` is striaght line as follows, where `theta = tan^(-1) 0.5` and `OA = 1.0` (S.I. units) Assuming `DeltaH^(@)` is independent of temperature, the equilibrium constant at 298 K will be:

Options

A. `10.002 xx 10^(9)`
B. `3.79 xx 10^(8)`
C. `7.96 xx 10^(9)`
D. `9.96 xx 10^(9)`

Answer

D
