Questions from chapter chemical thermodynamics. NCERT solutions from chemistry chapter chemical thermodynamics.Questions from past competitive exams from chemical thermodynamics. Questions from IIT,NEET etc. exams from chapter chemical thermodynamics. In this video we will cover:-
Question 1:-The first law of thermodynamics for isothermal process is:(a) q=-W (b) Δ U = W (c) Δ U = q v (d) Δ U =-q v
Question 2:-The process is spontaneous at the given temperature, if:(a) ΔH is +ve and ΔS is –ve (b) ΔH is-ve and ΔS is +ve (c) ΔH is +ve and ΔS is +ve (d) ΔH is +ve and ΔS is equal to zero.
Question 3:-The combustion of benzene (l) gives CO 2 (g) and H 2 O (l). Given that heat of combustion of benzene at constant volume is –3263.9 kJ mol –1 at 25° C ; heat of combustion (in kJ mol –1 ) of benzene at constant pressure will be - (R = 8.314 JK –1 mol –1 )
Question 4:-An isolated box, equally partitioned contains two ideal gases A and B as shown. When the partition is removed, the gases mix. The changes in enthalpy (ΔH) and entropy (ΔS) in the process, respectively, are:(a) zero, positive (b) zero, negative (c) positive, zero (d) negative, zero
Question 5:-A piston filled with 0.04 mol of an ideal gas expands reversibly from 50.0 mL to 375 mL at a constant temperature of 37.0 o C. As it does so, it absorbs 208 J of heat. The values of q and w for the process will be: (R = 8.314J/ mol K, ln 7.5 =2.01) (a) q=+208J,w=−208J (b) q=−208J,w=−208J (c) q=−208J,w=+208J (d) q=+208J,w=+208J
Question 6:-Enthalpy of sublimation of iodine is 24 cal g –1 at 200 °C. If specific heat of I 2 (s) and l 2 (vap.) are 0.055 and 0.031 cal g –1 K –1 respectively, then enthalpy of sublimation of iodine at 250°C in cal g –1 is :(a) 2.85 (b) 22.8 (c) 11.4 (d) 5.7
Question 7:-For a given reaction, ΔH=35.5KJmol -1 and ΔS=83.6JK -1 mol -1 . The reaction is spontaneous at: (Assume that ΔH and ΔS so not vary with temperature) (a) T less than 425K (b) T greater than 425K (c) All temperature (d) T greater than 298K
Question 8:- Under isothermal conditions, a gas at 300 K expands from 0.1 L to 0.25 L against a constant external pressure of 2 bar. The work done by the gas is: [Given that 1 L bar = 100 J] (a) 30 J (b) −30J (c) 5kJ (d) 25J
Question 8:- If one mole of ammonia and one mole of hydrogen chloride are mixed in a closed container to form ammonium chloride vapor, then (a) ΔH less than ΔU (b) No relationship (c) ΔH greater than ΔU (d) ΔH=ΔU
Question 9:- The heats of combustion of carbon and carbon monoxide are -393.5kJmol -1 and -283.5kJmol -1 respectively. The heat of formation (in kJ) of carbon monoxide per mole is (a) 676 kJ/mole (b) -676.5 kJ/mole (c) −110kJ/mole (d) 110.5 kJ/mole
