Thermochemistry
Thermochemistry can be considered as a branch of thermodynamics that deals with the connections between warmth, work, and various types of energy, formed because of different synthetic and actual cycles. Thermochemistry describes the energy changes that …
Exergonic Reaction
The term exergonic is derived from the Greek word in which ‘ergon’ means work and exergonic means ‘work outside’. Exergonic reactions releases work energy. Exergonic reactions are different from exothermic reactions, the one that releases only heat energ…

NH3 decomposes through an equilibrium reaction between NH3, H2, and N2. Only one of the options is correct:(A). The mechanism of the NH3 decomposition reaction must necessarily involve the collision of two NH3 molecules to induce a rearrangement of the atoms in this molecule.(B). The molecular weight of the NH3 decomposition reaction is 2 since two NH3 molecules must collide.(C). The rate of the NH3 decomposition reaction must be greater than that of NH3 synthesis, since the former requires two molecules to collide and the latter, four.(D). The NH3 decomposition reaction cannot occur in a single step.
Given the equilibrium A2 + B2 ⇌ 2 AB where k1 is the rate coefficient of the forward reaction and k-1 is the rate coefficient of the reverse reaction, with the forward reaction being first-order in A2 and B2, and the reverse reaction being second-order in AB. Equilibrium will be reached later if the relative values ​​of the constants are:(A) k1 high and k-1 high(B) k1 high and k-1 low(C) k1 low and k-1 high(D) k1 low and k-1 low
A 2-step reaction has the following mechanism: | 1. (fast) R2 R+R 2. (slow) R+Q K₂ P k_1 What series does it have? (A). v= - = (k + k1 − k-1)[R2][Q] (B). v=-k₁[R₂] + k₁[R]² - k₂[R][Q] (C). v=k₂[R]²[Q]² (D). v = k[R₂]1/2[Q]
