1 . Describe qualitatively, in terms of collision theory, the effect of concentration alterations on the level of response.
-If the concentrations of the reactants are increased, the pace of effect also increases. -The elements will be better together and there is a greater potential for the substances colliding. -Collisions will be more frequent-more collisions will certainly occur in a certain length of time.
2 . Explain why an increase in the pressure of a gas may raise the rate of reaction. When the pressure of your gas is usually increased, the molecules will be pushed nearer together. -The same quantity of molecules occupy a smaller amount.
-For a gaseous reaction, elevating the pressure is the same as raising the attention.
Therefore , for (for both) a particular time MORE collisions will take place and it will have MORE accident with energy GREATER than the activation energy. There will be MORE frequent crashes and the charge of effect will INCREASE.
3. What is a catalyst?
A substance that increases the price of chemical reaction without being consumed in the process.
5. Explain how a catalyst gives rise to an increased level of effect. A catalyst lowers the activation energy of the reaction by providing an alternative solution route for the reaction to follow and this alternative route includes a lower strength. This means less energy is required for the reactions to happen when the crashes occur, so more reactions will happen.
five. Draw and enthalpy account diagram intended for an exothermic reaction with and without a catalyst.
6th. Describe the benefits of using catalysts in industry
Using catalysts reduce strength consumption and so cost, while less account activation energy will be needed. As well as less energy required, less fossil gas is burnt and less co2 is produced into the atmosphere. Some factors make a process more effective, enhancing the percentage yield of an industrial preparation.
