If pressure is measured in bar and time in minutes, then Unit of rate = bar min-1 Rate = k(pCH3OCH3)3/2 ⇒ k = Therefore, unit of rate consta...
The decomposition of NH3 on platinum surface is represented by the following equation. 2NH3(g) + Pt → N2(g) + 3H2(g) Therefore, Rate = - = = ...
The initial rate of the reaction is Rate = k[A][B]2 = (2.0 × 10-6 mol-2L2s-1) (0.1 mol L-1) (0.2 mol L-1)2 = 8.0 × 10-9 mol-2L2s-1 When [A]...
(i) Given rate = k[NO]2 Therefore, order of the reaction = 2 Dimension of k = = = = L mol-1 s-1 (ii) Given rate = k[H2O2][I-] Therefo...
Correct answer: (d) None of these Explanation: Consider, figure.png no plane can pass in such a way that molecule has symmetry. Similarly f...
Correct answer: (a) I-enantiomers; II-diastereomers; III-enantiomers Explanation: figure.png
Correct answer: (a) Explanation: The enol form of acetone is with D2O it gives
Correct answer: (b) Explanation: The order of carbocation stability is
Correct answer: (d) Explanation: Stability of Alkene ∝ No. of H-atoms or more hyper conjugation.
Correct answer: (c) C6H5OH Explanation: Phenol is less acidic than H2CO3 so reaction does not favours in forward direction.
μ = 9.0 × 10–4 kg/m T = 900 N V = = = 1000 m/s f1 = 500 Hz f = 550 = 500 ......(i) = 500 .....(ii) (ii) (i) = 50 ℓ = = 1...
hT = hR = 160 ......(i) d = d = d = = 0 + = 0 = x = 80 m dmax = = = 8 x 2 x √2 x 2√2 = 64 km
We know that figure.png KE = PE y = = A sin ωt figure.png t = = x = 8
B = - = - = - = h = = h h = 500
Correct answer: (3) 245 Ω Explanation: figure.png 0.02i Rg = 0.98i x 5 Rg = 245 Ω
Correct answer: (b) 2-10% Explanation: Approximately how much of the solar energy that falls on the leaves of a plant is converted to chemical ene...
Correct answer: (c) Ether upright or inverted Explanation: Pyramid of number in grassland or forest or pond ecosystem is upright. In parasitic foo...
Correct answer: (b) Tropical rain forests Explanation: Tropical rain forests ecosystems is most productive in terms of net primary production.
Correct answer: (a) Spirogyra Explanation: Spirogyra, Volvox and Nostoc are producers. Agaricus is a fungus.
