If Rate = $K {[N O]}^{a} {[H_{2}]}^{b}$

Case I => $7 * 1 0^{- 9} = K {(8 * 1 0^{- 5})}^{a} {(8 * 1 0^{- 5})}^{b}$

Case II => $2.1 * 1 0^{- 8} = k {(24 * 1 0^{- 5})}^{a} {(8 * 1 0^{- 5})}^{b}$

Therefore, $\frac{7 ? * 1 0^{- 1}}{2.1} = {(\frac{1}{3})}^{a}$

or ${(\frac{1}{3})}^{1} = {(\frac{1}{3})}^{a} ∴ a = 1$

Ans. = 1
