Question

Why is the reaction spontaneous at T>425k. Why at that number and why is it less than T ?

Answer 1

Answer #1

DG0 = DH0 - TDS0

for a spontaneous process, minimum DG0 = 0.

0 = (35.5*10^3) - (t*83.6)

T = temperature = 425 k

if temperature is greater than 425 k , the process is spontaneous.

answer: B

54. During a spontaneous chemical reaction, it is found that ASsys < 0. This means a. AS surt < 0 and its magnitude is < ASsys. b. AS sur < 0 and its magnitude is > ASsys. AS surr > 0 and its magnitude is < ASsys. ASgurr > 0 and its magnitude is > ASsys. an error has been made, because Ssys > 0 by necessity for a spontaneous process.
