a.
Interpretation Introduction
For the below compound, Fischer projection formula has to be drawn.
Concept introduction:
Fischer projections:
In Fischer projection, the chirality center of the organic compounds are drawn using the following convention. First, the carbon atom is placed at the meeting point of the two lines of the cross. In a tetrahedron structure, the horizontal bonds indicate forward and denoted by wedges. The vertical bonds indicate backward and denoted by dashed lines. Finally, Fischer projection structure is abbreviated by cross formula.

- 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.arrow_forwardGiven 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.
