Correct Answer - B
`(k_(T_(2)))/(k_(T_(1)))=(mu)^(DeltaT//10)`
`(10^(-3))/(k_(T_(1)))=(mu)^(10//10)=2`
`k_(T_(1))=(10^(-3))/(2)=0.5xx10^(-3)=5xx10^(-4)"min"^(-1)`

Rate of reaction is given by the equation Rate = `k[A]^(2)[B]` What are the units for the rate and rate constant for the section?

Units of rate ( R) : Moles `L^(-1)s^(-1)` Units of `k:L^(2)mol^(-2)s^(-1)`

The rate of reaction: `2NO + Cl_(2) rarr 2NOCl` is given by the rate, equation rate `= k[NO]_(2)[Cl_(2)]`. The value of the rate constant can be incre

Correct Answer - A a) The value of rate constant depends upon temperature and not upon the initial concentration of reactants and products.

Assertion: Rate of reaction doubles when the concentration of the reactant is doubled if it is a first order reaction. Reason: Rate constant also beco

Correct Answer - C c) Correct reason. Rate constant remains constant for the reaction and is independent of the initial concentration of the reason.

The rate constant of the first order, decomposition of `N_(2)O_(5)` at `25^(@)` is `3.00 xx 10^(-3) min^(-1)`. If the initial concentration of `N_(2)O

According to available data: `a=2.0 xx 10^(-3) mol L^(-1), (a-x) = 5.0 xx 10^(-4) mol L^(-1), k=3.0 xx 10^(-3) min^(-1)` `t=(2.303)/k log a/(a-x) = (2.303)/(3 xx 10^(-3) min^(-1)) = 4.62...

Match order of the reaction (in List-I) with the corresponding rate constant (in List II). `{:("List I (order)","List II (rate constant)"),((A)"Zero",

Correct Answer - A-r; B-s ; C-q; D-p Zero order x=kt First order `K=1/t"In"a/(a-x)` Second order `K=1/t[1/(a-x)-1/a]` Third order `K=1/(2t)[1/(a-x)^2-1/a^2]`

`T_(50)` of first order reaction is 10 min. starting with 10 `"mol"^(-1)` rate after 20 min is :

Correct Answer - B Remainin concetration of reactant after 20 min `=(1)/(4)xx102.5"mol"L^(-1)` `"Rate"=kxx["Reactant"]=(0.693)/(t_(1//2))xx["Reactant"]` `=(0.693)/(10xx2.5=0.0693xx2.5 "mol"L^(-1) min^(-1)`

(a) For a reaction `ABrarrP` , the rate law is given by, `r=k[A]^(1//2)[B]^(2).` What is the order of this reaction? (b) A first order reaction is fou

(a) `0.5+2=2.5` (b) For the first order reaction, `t_(1//2)=(0.693)/(K)=(0.693)/(5.5xx10^(-14)S^(-1))=1.26xx10^(13)S.`
