Given below is the data for the reaction $$2\text{NO}(g) \rightleftharpoons \text{N}_2(g) + \text{O}_2(g)$$,where $$k_f$$ and $$k_b$$ are the rate constants of the forword and reverse reaction respectively,  The reaction is

A

exothermic and $$K_{eq}$$ at 1400 K is $$3.79 \times 10^{-6}$$

B

endothermic and $$K_{eq}$$ at 1400 K is $$2.63 \times 10^{-5}$$

C

exothermic and $$K_{eq}$$ at 1400 K is $$1.8 \times 10^5$$

D

endothermic and $$K_{eq}$$ at 1500 K is $$9.28 \times 10^{-4}$$
