The constant is the reaction rate constant or rate coefficient of the reaction. Its value may depend on conditions such as temperature, ionic strength, surface area of an adsorbent, or light irradiation. If the reaction goes to completion, the rate equation for the reaction rate applies throughout the course of the reaction.

Answers (1) For motion, horse applies force on the ground and thus the frictional force of the ground pushes the horse forward (action-reaction pair). Thus horse applies force on the cart and cart applies backward force on the horse but due to unbalanced force, the horse moves in the forward direction. Posted by.

Nucleophilic substitution reactions on alkyl halides involve two main reactions sn1 & sn2 reactions. In the last part of this blog, I will explain a brief difference between Sn1 and Sn2 reactions as a conclusion. Electrophile/Nucleophile An electrophile is basically a species that reacts with the nucleophile.

Photosynthesis is considered an endothermic reaction, because during the process of photosynthesis, energy from the sun or sunlight is being absorbed. Any chemical reactions that absorb heat energy from the surroundings to form products is termed the endothermic reaction. Why some reactions are exothermic and some are endothermic?

Solution In the presence of sulphuric acid (H 2 SO 4 ), KI produces HI Since is an oxidizing agent, it oxidizes HI (produced in the reaction to I 2). As a result, the reaction between alcohol and HI to produce alkyl iodide cannot occur. Therefore, sulphuric acid is not used during the reaction of alcohols with KI.

The Immune System How It Works Types Role of Antigens Role of Antibodies An antigen is a molecule that stimulates an immune response by activating leukocytes (white blood cells) that fight disease. Antigens may be present on invaders, such as bacteria, viruses, parasites, fungi, and transplanted organs, or on abnormal cells, such as cancer cells.

Antigen–antibody reactions are a mainstay for the rapid detection of proteins. Antibodies recognize proteins based on their structure as well as content, and can be very specific, binding to only a small part of an antigen (known as the epitope), and discriminating between highly similar epitopes.

What will happen if a solution of sodium hydrocarbonate is heated ? Give the equation of the reaction involved. Medium Solution Verified by Toppr 2 SodiumhydrogencarbonateNaHCO 3 → SodiumCarbonateNa 2CO 3 + WaterH 2O+ CarbondioxidegasCO 2↑ When sodium hydrogen carbonate is heated we get sodium carbonate, water and carbon dioxide gas.

The meaning of ORDER OF A REACTION is a number that relates the rate of a chemical reaction with the concentrations of the reacting substances : the sum of all the exponents of the terms expressing concentrations of the molecules or atoms determining the rate of the reaction.

Since the leaving group (N 2) is thermodynamically very stable, these reactions are energetically favored. Those substitution reactions that are catalyzed by cuprous salts are known as Sandmeyer reactions. Fluoride substitution occurs on treatment with BF 4 (–), a reaction known as the Schiemann reaction. Stable diazonium tetrafluoroborate.
