Front (Question)

Feasibility of a chemical reaction can be predicted by

Back (Answer)

Thermodynamics

Front (Question)

Extent of a chemical reaction can be predicted by

Back (Answer)

Chemical equilibrium

Front (Question)

Assertion : diamond cannot be converted to graphite Reason : diamond is forever

Back (Answer)

The assertion and reason is false diamond can be converted to graphite

Front (Question)

The rate is always multiplied with -1 to make it a positive quantity

Back (Answer)

True

Front (Question)

Unit of rate is

Back (Answer)

Concentration time inverse/ atm s inverse

Front (Question)

Statement 1: Rate of a reaction depends on stochiometric coefficient Statement 2: rate of any species will be fixed value under given condition

Back (Answer)

Both statements are correct

Front (Question)

The rate of the reaction is CHCL3 +CL2 = CCL4 + HCL

Back (Answer)

Rate = k [ CHCl3] [ Cl2]^1/2

Front (Question)

The rate ofthe reaction is CH3COOC2H5 + H2O = CH3COOH + C2H5OH

Back (Answer)

Rate = k[ CH3COOC2H5] ^1 [H20]^0

Front (Question)

Assertion: rate law of a reaction cannot be determined by mere looking of a chemical reaction Reason : it must be obtained experimentally

Back (Answer)

Both assertion and reason are true

#10

Front (Question)

Example of consecutive reaction is

Back (Answer)

Oxidation of ethane

#11

Front (Question)

Example of reverse reaction and side reaction

Back (Answer)

Nitration of phenol to yield o nitro phenol and p nitro phenol

#12

Front (Question)

Statement1: the reaction with collision of three or more molecules are rare to proceed Statement2 : 2NO +O2 = 2NO2

Back (Answer)

Both statements are correct

#13

Front (Question)

The order of the given reaction is KCLO3 + 6FeSO4 +3 H2SO4 = KCL +3 Fe2(SO4)3 +3H20

Back (Answer)

#14

Front (Question)

In Decomposition of hydrogen peroxide the rate determining step is

Back (Answer)

H2O2 + I^- = H2O + IO ^-

#15

Front (Question)

Statement1: order is applicable to elementary as well as complex Rn but Statement2 : molecularity is applicable only to elementary rn

Back (Answer)

Both statements are true

#16

Front (Question)

Factors influencing the rate of the reaction is

Back (Answer)

Concentration of reactant Rate expression and rate constant Order of a reaction Molecularity of a reaction

#17

Front (Question)

The integrated rate eq for 1st order rn Is

Back (Answer)

[R] = -KT +[ Ro]

#18

Front (Question)

Statement 1: some enzyme catalyzed rn and reaction which occur on the metal surface are examples of zero order rn Statement2: zero order reactions are very rare

Back (Answer)

Both statements are true

#19

Front (Question)

Why is 2 NH3 = N2 + 3H2 (in presence of Pt catalyst and 1130 K) a zero order rn ?

Back (Answer)

This reaction is catalyzed by Pt , at high pressure the metal surface is saturated with gas molecules and further changes in reaction condition cannot alter the amountt of ammonia making the rate of reaction concentration independent

#20

Front (Question)

Examples of zero order rn

Back (Answer)

NH3 = N2 + H2 ( in presence of Pt and at 1130K) Thermal Decomposition of HI on gold surface

#21

Front (Question)

The integrated form of 1st order reactions are

Back (Answer)

[R] = [Ro] e ^ (-kt) K = 2.303 /t log [ Ro]/ [ R]

#22

Front (Question)

Examples of first order reaction

Back (Answer)

Hydrogenation of ethene All artificial and natural radioactive decay of unstable nuclei Decomposition of N2O5 and N2O

Back (Answer)

[Ro] /2 k

#24

Front (Question)

For first order reaction half life is

Back (Answer)

0.693 / k
