What is the minimum temperature required for the spontaneous conversion of one m

Question

What is the minimum temperature required for the spontaneous conversion of one mole of CCI For the reaction which is spontaneous only high temperatures one would predict that: For a reaction that has an equilibrium constant 2.0 Times 10-3, which of the following statements must be true? In the voltaic cell that is represented as which of the following statements is false. How many moles of electrons are produces from a current of 15.0 amps in 15.00 minutes? What is the value of "n" for the following redox reaction? A reaction is spontaneous when: At 25 degree C, calculate the voltage of the cell

Explanation / Answer

22. DG = DH-TDS

for spontaneous process T>DH/DS

573/1.64 = T

T = 76.39 C

a) 76C   <----------- answer

23. if DH is + and DS is + . so that at high temperature reaction is spontaneous.

a) DH is + and DS is +   <----------- answer

24) DG0 = -RTlnK

if K = 2.0*10^-3 then DG0 = +ve

b) DG positive <----------- answer

25) b) copper electrode is the anode

26) q = it

    = 15*15*60
   = 13500 c
1 electron = 1.602*10^-19 c

? electrons = 13500 c
No of electrons = 8.426*10^24

No of moles = 0.14 mole

answer : b)0.14 mole

27) e)10

28) a) DG0is negative,E0is positive.
