Please help with 2.4. It must be solved using the Euler-Lagrange
equation. The answer is a right cylinder, but I'm not even sure how
to use the E-L equation to get that answer. Thank you!

Question 9 When 0.0031 moles of a weak acid are dissolved in enough water to make 0.500 L, the pH of the resulting solution is 4.36 Calculate K Incorrect Mark 0.00 out of 1.00 Answer 2.71e-7 Flag question
I solved A but I'm confused on
how to solve B if someone could please help me I would highly
appreciate it
Acetylene, C2H2, can be converted to ethane, C2H6, by a process known as hydrogenation. The reaction is C2H2(g) + 2H2(g) = C2H6(g) Given the following data at standard conditions (all pressures equal to 1 atm and the common reference temperature 298 K), what is the value of Kp for this reaction? Substance AG: (kJ/mol) 209.2 C2H2(g) H2(g) C2H6(g)...
I'm not sure how to answer. how do I figure out the
