No worries I will provide you Amrita Vishwa Vidyapeetham, B.Tech. Electronics and Communications Engineering First semester periodical test-II chemistry question paper so that you can solve it easily.

Here is the exam paper

Part A (5*2=10 marks)
1.What is the maximum degree of freedom possible for a single component system?

2.In Ellingham diagram, the metal to metal oxide curve for Hg shows a sudden abrupt change at approximately 356 degree centigrade .give reason.

3.Predict the number of phases containing sand, charcoal, water, water vapour

4.Find the number of degrees of freedom
NH3(g)+HCl(g)(excess)-->NH4Cl

5.Write the conditions which facilitate the formation of meta stable curve.

Part B (40 marks)
6.Construct a phase diagram for a metal alloy system of components A and B. The melting point of a component A is 275 degree centigrade and that of a B is 103 degree centigrade. The eutectic point of as system has been found to be 93 degree centigrade. Find out the number of degrees of freedom at different points, curves and areas. [5 Marks]

7.Why the metal oxide curves in Ellingham diagram show positive slope? Justify your answer with thermo dynamical concepts.[6 Marks]

8. Carbon dioxide is good reducing agent below 710 degree centigrade whereas carbon monoxide is preferred above this temperature .justify. [4 Marks]

9. a)Explain the application of phase rule in Pattinson's process.[6 Marks]
b)Discuss the applications and limitations of phase rule. [4 Marks]

10.Define phase rule. Explain the terms involved with examples. With the help of a neat sketch, explain in detail the applications of phase rule to a one component system. [10 Marks]

11.Define and compare the terms triple point and eutectic point with examples. [5 Marks]
