Answer Three questions only! (01 must be include) Q1: Answer the following (30 point): 1- Chemical kinetics is the study of chemical reaction rates and reaction mechanisms. a- Yes, b- No, c- Maybe 2- Energy is taken in from the surrounding. a- Exothermic, b-Endothermic, c- both of them 3- The Temperature (T) is one of the key process variables. a- Yes, b- No, c- Maybe 4- tells us how fast a number of moles of one chemical species are being consumed to form another chemical species. a- The rate of reaction, b- The conversion, c- The Yield 5- Relative Rates is: a- of formation of a given species (e.g., A) is the sum of the rate of reactions of A all the reactions in which A is either a reactant or product in the system. b- the algebraic equations that apply to a given rea ion. c- tell us how fast one species is disappearing or appearing relative to the other species in the given reaction. 6- Temperature, Pressure and concentration. a- Factors Affecting the cooking. b- Factors Affecting of the type of reaction system. C- Factors Affecting Reaction Rates. 7- is the amount of desired product produced relative to the amount that would have been formed if there were no byproducts and the main reaction went to completion. a- Conversion, X, b-Yield, Y, C- Rate of Reaction 8- the reactants materials are: a- the disappearing materials. b- the products materials. C- the catalyst materials. 9- The equilibrium constant decreases with increasing temperature for exothermic reactions and increases with increasing temperature for endothermic reactions. a- False, b-True, c- no one 10- the volumetric flow rate unit is (volume/time). a- False, b- True. c- no one
