In nature, one common strategy to make thermodynamically unfavorable reactions proceed is to couple them chemically to reactions that are thermodynamically favorable. as long as the overall reaction is thermodynamically favorable, even the unfavorable reaction will proceed.
part a: consider these hypothetical chemical reactions:
a⇌b,δg= 11.9 kj/mol
b⇌c,δg= -26.7 kj/mol
c⇌d,δg= 7.30 kj/mol
what is the free energy, δg, for the overall reaction, a⇌d?

Why is the bond angle in a water molecule less than the bond angle of methane? a. the central oxygen atom in water has two lone pairs of electrons, whereas the central carbon atom in methane has no lone pairs. b. the central hydrogen atom in water has one lone pair of electrons, whereas the central carbon atom in methane has two lone pairs. c. the central oxygen atom in water has four lone pairs of electrons, whereas the central carbon atom in methane has only one lone pair. d. the central oxygen atom exerts more repulsive force on surrounding atoms than the central carbon atom in methane does. reset next
