Temperature is one of the most influencing factors on the rate of chemical reactions. However, sometimes it is observed that the actual effect of temperature on the rate of a reaction is much smaller than expected. Explain possible reasons

Homework Answers

Answer #1

=> Usually, an increase in temperature is accompanied by an increase in the reaction rate.

=> Temperature is a measure of the kinetic energy of a system, so higher temperature implies higher average kinetic energy of molecules and more collisions per unit time.

=> A general rule of thumb for most (not all) chemical reactions is that the rate at which the reaction proceeds will approximately double for each 10°C increase in temperature. => Once the temperature reaches a certain point, some of the chemical species may be altered (e.g., denaturing of proteins) and the chemical reaction will slow or stop.

Increased temperature increases the rate of all chemical reactions. However, increased temperature in some cases increases and in other cases decreases the proportion of product relative to unreacted starting material. Draw reaction energy diagrams for exergonic and endergonic reactions, and explain why in both cases higher temperature increase the reaction rate, but has opposite effect on proportion of product.

Chemical Reactions Types and Their Equations Making Heat with Chemical Reactions Have you ever wondered how an instant heat pack works? A disposable heat pack works by a chemical reaction that combines iron in the package with oxygen from the air when the outer packaging is removed producing iron oxide. You have probably seen the product of this reaction in what is commonly called rust. The reaction releases heat, which allows the pack to reach a sufficient temperature that is...

It is from the book Elementary Principles of Chemical Processes, 4th Edition, Problem 5.66 The quantity of sulfuric acid used globally places it among the most plentiful of all commodity chemicals. In the modern chemical industry, synthesis of most sulfuric acid utilizes elemental sulfur as a feedstock. However, an alternative and historically important source of sulfuric acid was the conversion of an ore containing iron pyrites (FeS2) to sulfur oxides by roasting (burning) the ore with air. The following reactions...
