Question

In the reaction 2N2 O5arrow 4NO2 + O2 the rate is expressed as (i)(d[N2O5]/dt) k1[N2O5] (ii)(d[NO2]/dt)=k2[N2O5] 0 (iii)(d[O2]/dt)=k3[N2O5] Relation between k1 k2 and 3 is (A) 2k1 = 4k2 = k3  (B) 2k1 =k2 = 4k3  (C) 2k1 = k2 = 2k3  (D) k1 = 4k2 = 2k3

Tardigrade Admin · Accepted Answer

Rate = (1/2) (d[N2O5]/dt) =(1/4) (d[NO2]/dt) =(d[O2]/dt) Rate =(1/2)k1[N2O2]=(1/4)k2[N2O5]=(1/4)[N2O5]=K3[N2O5] On dividing all the terms by [N2O5] and multiplying by 4 we get, 2k1 = k2 = 4k3

Q. In the reaction $2 N_{2} O_{5} \to 4 N O_{2} + O_{2}$ the rate is expressed as
(i) $\frac{d [ N _{2} O _{5} ]}{d t} k_{1} [N_{2} O_{5}]$
(ii) $\frac{d [ N O _{2} ]}{d t} = k_{2} [N_{2} O_{5}]$ 0
(iii) $\frac{d [ O _{2} ]}{d t} = k_{3} [N_{2} O_{5}]$
Relation between $k_{1} k_{2}$ and $3$ is

$2 k_{1} = 4 k_{2} = k_{3}$

$2 k_{1} = k_{2} = 4 k_{3}$

$2 k_{1} = k_{2} = 2 k_{3}$

$k_{1} = 4 k_{2} = 2 k_{3}$

Q. In the reaction 2N2​O5​→4NO2​+O2​ the rate is expressed as (i)dtd[N2​O5​]​k1​[N2​O5​] (ii)dtd[NO2​]​=k2​[N2​O5​]0 (iii)dtd[O2​]​=k3​[N2​O5​] Relation between k1​k2​ and 3 is

2k1​=4k2​=k3​

2k1​=k2​=4k3​

2k1​=k2​=2k3​

k1​=4k2​=2k3​

Rate =21​dtd[N2​O5​]​=41​dtd[NO2​]​=dtd[O2​]​ Rate =21​k1​[N2​O2​]=41​k2​[N2​O5​]=41​[N2​O5​]=K3​[N2​O5​] On dividing all the terms by [N2​O5​] and multiplying by 4 we get, 2k1​=k2​=4k3​

Q. In the reaction $2 N_{2} O_{5} \to 4 N O_{2} + O_{2}$ the rate is expressed as
(i) $\frac{d [ N _{2} O _{5} ]}{d t} k_{1} [N_{2} O_{5}]$
(ii) $\frac{d [ N O _{2} ]}{d t} = k_{2} [N_{2} O_{5}]$ 0
(iii) $\frac{d [ O _{2} ]}{d t} = k_{3} [N_{2} O_{5}]$
Relation between $k_{1} k_{2}$ and $3$ is

$2 k_{1} = 4 k_{2} = k_{3}$

$2 k_{1} = k_{2} = 4 k_{3}$

$2 k_{1} = k_{2} = 2 k_{3}$

$k_{1} = 4 k_{2} = 2 k_{3}$
