For homework problem 4.9 part C, I used the given concentration
values to solve for the Q value. Then, I plugged this into the
equation to solve for delta G and used -30.5 kJ/mol for the
delta G naught value. I'm not sure exactly what this problem is
asking to solve for since I found the value for delta G, but it
keeps marking my answer as incorrect.</div>

<p>which is in J/mol. K=[ADP][P]/[ATP]= (0.1)(0.25)/(0.0000001)</p>

<p>When I plut that into my equation I get -205.7 J/mol.</p>
