Question

25)( quad 280_{2}+0_{2} longrightarrow 230_{3} )
( begin{aligned} frac{d[cos ]}{d t} &=100 frac{d(0,1}{d t}=& 1 / 2 frac{d(503]}{d t} &=4, x 100 &=50 end{aligned} )

# 9 . 2 (C) 3:1 (D) 3:10 (B) 2:1 UTAU of disappearance of the reactant. Thus, X:yis : Rate of formation of SO3 in the following reaction 2502 + O2 + 250, is 100 g min). Hence rate of disappearance of Oz is : (A) 50 g mint (B) 40 g min-1 (C) 200 g mini (D) 20 g min-1 A-4. aA + bB - Product, dx/dt = k [A]a [B] . If concentration of A is doubled, rate is tour times. It
