Question

At 350K One biochemical reaction has a Gibb's free energy of -345Kj/mol and a second reaction has a Gibb's free energy of -620Kj/mol

what is the ratio of their equilibrium constants at 350K?

Anyone know what it means by ratio?

I used the equation

Dela G = -(RT)ln(Keq)

and for reaction one got a keq of 3.09*10^51
and for reaction two got a keq of 3.41*10^92

I added their gibb's free energy and then applied the equation and got 1.06*10^144
my assumption is that these reactions are coupled thus they would work together in pushing towards product formation, am I incorrect in th

Answer 1

I'm pretty sure ratio just means one divided by the other

Answer 2

ratio of seats (10) to people (20)

10/20 = 1/2

1/2 seat/person

Answer 3

I know what a ratio is, but how would I set this ratio up

Answer 4

dividing one by the other seems pretty meaningless

Answer 5

i know it is meaningless

Answer 6

unless you're just trying to compare them

Answer 7

yeah, I'm thinking the same, occam's razor, I will probably just ask my TA or something

Answer 8

i think you got the values wrong though

Answer 9

well I didnt make a mistake in the math, are you suggesting that I'm using the wrong equation?

Answer 10

also both equations seem pretty exothermic, thus high dissociation constants seem reasonable as the reactions will strongly push towards products

Answer 11

I mean reactions

Answer 12

not equations

Answer 13

oh nvm i made a mistake you're right
