Consider the reaction: 3A → 4C Initially, and at some fixed temperature, the reaction proceeds at such a rate that 200 millimoles of A are consumed in 1 minute and 47 seconds. The reaction takes place in 1.00 L. a. Express the rate of the reaction as a function of the rates of appearance and disappearance of A and C. b. Find the initial rate of the reaction. Experimental data are expressed in the table below. t (s) [A], M 0.00 4.20 10.0 3.20 20.0 2.45 30.0 1.87 40.0 1.42 50.0 1.09 *c. Determine the order of the reaction. Is the reaction elementary? e. Find the rate constant and express the rate law for this reaction. f. Find the period of time between the 7th half-life and 8th half-life. ¥h. What will be the time when 37.0% of A will have reacted (t37%)? ¥i. What will be the concentration of [C] at t37%? A decomposes thermally, it is observed that k varies as : (No calculations are needed for this part) k (s-) т (K) 5.10 x 10-3 302 2.60 x 10-2 451 3.10 x 10-2 479 4.10 x 10-2 528 *1. Explain why k increases when we increase the temperature. *m. If, for the same reaction, at a particular temperature, we were to add a catalyst, would Ea, A, k and v be larger, smaller, equal? Explain.
Neutral Amino Acids
Amino acids which do not have any charge on them are neutral amino acids.
Globular Protein
The globular proteins refer to the shape of protein specifically spherical in nature apart from spherical form fibrous, disordered and membrane-bound proteins exist. These globular proteins are miscible in water and form a colloidal solution rather than other types which might not exhibit solubility. Many classes of the fold are found in globular proteins, which render them a sphere shape. Globular fold containing proteins usually are referred to by the term globin.
Dimer
Dimers are basic organic compounds, which are derivates of oligomers. It is formed by the combination of two monomers which could potentially be strong or weak and in most cases covalent or intermolecular in nature. Identical monomers are called homodimer, the non-identical dimers are called heterodimer. The method by which dimers are formed is known as “dimerization”.
Dipeptide
A dipeptide is considered a mixture of two distinct amino acids. Since the amino acids are distinct, based on their composition, two dipeptide's isomers can be produced. Various dipeptides are biologically essential and are therefore crucial to industry.
