(C)act as a promotor
(D) always appear in the chemical equation

Hydrogen peroxide in its reaction with KIO_(4) and NH_(4)OH respectively, is acting as a

Consider the following reaction A to P1, B to P2 , C to P3 , D to P4 , The order of the above reaction are a,b,c and d, respectively . The following graph is obtained when log [rate ] vs. log [conc.] are plotted : Among the following the correct sequence for the order of the reaction is :

Assertion (A): Hydrolyiss of ethyl acetate in the presence of acid is a reaction of first order whereas in the presence of alkali, it is a reaction of second order. Reason (R ): Acid acts as catalyst only whereas alkali act as one of the reactant.

We know that balancing of a chemical equation is entirely bases on law of conservation of mass. However the concept of Principle of Atom Conservation (POAC) can also be related to law of consevation of mass in a chemical reaction. So, POAC can also act as a technique for balancing a chemical equation. For example, for a reaction: ABC_(3) rarr AB+C_(2) On applying POAC for A , B and C and related the equations , we get : (n_(ABC_(3)))/(2) =(n_(AB))/(2) =(n_(C_(2)))/(3) ( n_(x) : number of moles of X) Thus , the cofficients of ABC_(3) , AB and C_(2) in the balanced chemical equation will be 2,2 and 3 respectively and the balanced chemical equation can be represented as , 2ABC_(3) rarr 2AB + 3C_(2) Which of the following statements jis correct balanced chemical equation, pA+qB_(2) rarr rA_(2)B_(5)

An organic compound A’ with molecular formula C_(7)H_(7)NO reacts with Br_(2) /aqKOH to give compound B’, which upon reaction with NaNO_(2) & HCl" at "O^(@) C gives C’. Compound C’ on heating with CH_(3)CH_(2)OH gives a hydrocarbon D’. Compound B’ on further reaction with Br_(2) water gives white precipitate of compound E’. Identify the compound A, B, C, D&E, also justify your answer by giving relevant chemical equations.

During developing of an exposed camera film, one step involves in the following reaction : Which of the following best describes the role of quinol? (a)It acts as an acid (b)It acts as reducing agent (c)It act as oxidant (d)It acts as a base

A particle of mass 70 g, moving at 50 cm/s , is acted upon by a variable force opposite to its direction of motion. The force F is shown as a function of time t (a) its speed will be 50 cm/s after the force stops acting (b) its direction of motion will reverse (c) its average acceleration will be 1 m//s^2 during the interval in which the force acts its average acceleration will be 10 m//s^2 during the interval in which the force acts

Ammonia gas dissolves in water to form NH_(4)OH . In this reaction water acts as

The rate of SN^2 reaction depends on the effectiveness of the nucleophile in ejecting the leaving group. Nucleophilicity is the affinity for C atom, while basicity is the affinity for proton. In both cases, a new bond is formed. If a new bond is formed between the anion and proton, the specied acts as a base. If a new bond is formed between the anion and C atom, the species acts as nucleophile. Which of the following statements is wrong ? Nucleophile order of the following in weakly polar aprotic solvents, e.g., acetone is :

For the chemical reaction A + 2B rarr C , the rate of reaction is increased by 2.82 times when the concentration of A is doubled and increased by 9 times when the concentration of B was tripled. What is the order with respect to B and A and total order ?
