Answer: The rate of appearance of 
is 
Explanation:
Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.
The rate in terms of reactants is given as negative as the concentration of reactants is decreasing with time whereas the rate in terms of products is given as positive as the concentration of products is increasing with time.
Rate in terms of disappearance of HBr = ![-\frac{1d[HBr]}{2dt}Rate in terms of appearance of [tex]H_2](https://tex.z-dn.net/?f=-%5Cfrac%7B1d%5BHBr%5D%7D%7B2dt%7D%3C%2Fp%3E%3Cp%3ERate%20in%20terms%20of%20appearance%20of%20%5Btex%5DH_2)
= ![\frac{1d[H_2]}{dt}](https://tex.z-dn.net/?f=%5Cfrac%7B1d%5BH_2%5D%7D%7Bdt%7D)
Rate in terms of appearance of = ![\frac{1d[Br_2]}{dt}](https://tex.z-dn.net/?f=%5Cfrac%7B1d%5BBr_2%5D%7D%7Bdt%7D)
![-\frac{1d[HBr]}{2dt}=\frac{d[H_2]}{dt}=\frac{d[Br_2]}{dt}](https://tex.z-dn.net/?f=-%5Cfrac%7B1d%5BHBr%5D%7D%7B2dt%7D%3D%5Cfrac%7Bd%5BH_2%5D%7D%7Bdt%7D%3D%5Cfrac%7Bd%5BBr_2%5D%7D%7Bdt%7D)
Given :
![-\frac{1d[HBr]}{dt}=0.140Ms^{-1}](https://tex.z-dn.net/?f=-%5Cfrac%7B1d%5BHBr%5D%7D%7Bdt%7D%3D0.140Ms%5E%7B-1%7D)
The rate of appearance of ;
![\frac{1d[Br_2]}{dt}=-\frac{1d[HBr]}{2dt}=\frac{1}{2}\times 0.140=0.0700Ms^{-1}](https://tex.z-dn.net/?f=%5Cfrac%7B1d%5BBr_2%5D%7D%7Bdt%7D%3D-%5Cfrac%7B1d%5BHBr%5D%7D%7B2dt%7D%3D%5Cfrac%7B1%7D%7B2%7D%5Ctimes%200.140%3D0.0700Ms%5E%7B-1%7D)
Thus rate of appearance of is
Which mathematical relationship allows calculation of the equilibrium constant of a reaction if you know the standard change in Gibbs Free Energy ΔG is related to Q by the equation ΔG=RTlnQK. If ΔG < 0, then K > Q, and the reaction must proceed to the right to reach equilibrium
<h3>What is
Gibbs Free Energy?</h3>
The maximum amount of work that may be accomplished by a thermodynamically closed system at constant temperature and pressure can be determined using the Gibbs free energy (also known as Gibbs energy; symbol: displaystyle G). Additionally, it offers a prerequisite for any processes like chemical reactions that might take place in such circumstances.
The maximum amount of non-expansion work that can be taken from a closed system (one that can interchange heat and work with its surroundings but not matter) at fixed temperature and pressure is known as the Gibbs free energy change, which is measured in joules in SI. This maximum is only possible with a fully reversible method.

Answer:
A thermoplastic is a polymer that becomes pliable or moldable above a specific temperature and returns to a solid state upon cooling. These are the linear or slightly branched long chain molecules. For examples, PVC, polystyrene, nylon,polyethylene etc.
