Which of the following chemical reactions is a decomposition reaction? (Here A, B, C and D represent any element/ molecule)

For the reaction 2NO + Br₂ → 2NOBr, the following mechanism is given

\(\rm NO \ + \ Br_2 \ \overset{Fast}{\rightleftharpoons} \ NOBr_2 \)

\(\rm NOBr_2 \ + \ NO \ \xrightarrow{Slow} \ 2NOBr\)

Hence rate law is

For a reaction CHCl₃ + Cl₂ → CCl₄ + HCl, the rate is given as Rate = k [CHCL₃] [Cl₂]^1/2, the order of the reaction will be 

The value of the rate constant for the gas phase reaction, 2NO₂ + F₂ → 2NO₂F is 38 dm³ mol^-1 s^-1 at 300 K. The order of the reaction is

Half life period of first order reaction is 20 minutes. How long will it take to 75% completion?

In a homogeneous catalytic reaction 1.0 M of a substrate band 1.0 μM of a catalyst yields 1.0 mM of a product in 10 s. The turnover frequency (TOF) of the reaction (s^-1) is

Consider the following two parallel irreversible first order reactions at temperature T,

where k1 and k2 are the constants and their values are 5 × 10-2 and 15 × 10-2 min-1 respectively, at temperature T. If the initial concentration of the reactant 'P' is 4 mol L-1, then the concentration of product 'R' after 10 min of reaction is _______ mol L-1. (Round off to two decimal places)

(Assume only P is present at the beginning of the reaction.)

If a plot of lnK vs. 1 / T, gives a straight line, what will be the slope (slope) of the straight line?

If the rate of reaction does not depends upon the initial concentration of reactant, the order of reaction is :

Consider the following reversible chemical reactions:

\({A_2}\left( g \right)\; + \;{B_2}\left( g \right)\begin{array}{*{20}{c}} {{K_1}}\\ \rightleftharpoons \end{array}\;2AB\left( g \right)\)      …. (1)

\(6AB\left( g \right)\;\begin{array}{*{20}{c}} {{K_2}}\\ \rightleftharpoons \end{array}3{A_2}\left( g \right) + 3{B_2}\left( g \right)\)        …. (2)

The relation between K₁ and K₂ is:
