Solution

The correct option is C $3$
$ϑ_{0} = k {[6]}^{a} {[H]}^{b}$
$ϑ_{1} = k {[6]}^{a} {[H]}^{b} 2^{a + b}$
$ϑ_{2} = k {[6]}^{a} {[H]}^{b} 2^{a}$
${\frac{ϑ_{1}}{ϑ_{0}} = 2^{a + b} = 8 ⟶ (1) \frac{ϑ_{2}}{ϑ_{0}} = 2^{a} = 2 ⟶ (2)}$
solving (1) and (2) is a system of linear equations: $a = 1, b = 2$
$∴$ net order $= 2 + 1 = 3$ .
