R = K [ A ] n [ B ] m 0.05= K (0.1) n (0.1) m ...(i) 0.1= K (0.2) n (0.1) m ...(ii) 0.05= K (0.1) n (0.2) m ...(ii) From eq. (ii) ÷ (i) 2=2n n=1 From eq. (iii) ÷ (i) 1=2m m=0 ∴ Rate law: R = K [ A ] and K =( R /[ A ])=(0.05/0.1)=0.5 s -1 K =0.5 s -1

Initial conc. of $A M L^{- 1}$	Initial conc. of $B$ in $M L^{- 1}$	Rate in $M L^{- 1} S^{- 1}$
$0.1$	$0.1$	$0.05$
$0.2$	$0.1$	$0.1$
$0.1$	$0.2$	$0.05$

Q. A+B⟶ Product For the above reaction following initial rates were given at various initial concentration Initial conc. of AML−1 Initial conc. of B in ML−1 Rate in ML−1S−1 0.1 0.1 0.05 0.2 0.1 0.1 0.1 0.2 0.05 Determine the rate constant.

R=K[A]n[B]m 0.05=K(0.1)n(0.1)m ...(i) 0.1=K(0.2)n(0.1)m ...(ii) 0.05=K(0.1)n(0.2)m ...(ii) From eq. (ii) ÷ (i) 2=2n n=1 From eq. (iii) ÷ (i) 1=2m m=0 ∴ Rate law : R=K[A] and K=[A]R​=0.10.05​=0.5s−1 K=0.5s−1

Q. $A + B ⟶ Product$
For the above reaction following initial rates were given at various initial concentration

Initial conc. of $A M L^{- 1}$ Initial conc. of $B$ in $M L^{- 1}$ Rate in $M L^{- 1} S^{- 1}$

$0.1$ $0.1$ $0.05$
