Reactant A gives K ($E_a=50.0\mathrm{kJ}\mathrm{mo}{\mathrm{l}}^{-1}$) and T ($E_a=65.0\mathrm{kJ}\mathrm{mo}{\mathrm{l}}^{-1}$) by parallel irreversible steps with equal pre-exponential factors ($R=8.314\mathrm{J}\mathrm{mo}{\mathrm{l}}^{-1}{\mathrm{K}}^{-1}$). Which statements are correct?

1. A[K]/[T] is greater than 1 at every temperature
2. B[K]/[T] increases when the temperature is raised
3. CAt 298 K, [K]/[T] $\approx 426$
4. DAt 373 K, [K]/[T] $\approx 126$
