Okay thank you sir
Youre right sir. Am i going to use this eqn Q=mc deltaT Where my change in temp will be 79.5-55 C?
The first and second question are related sir. But i cant see the use of the initial temp on the second question. To solve for the mass on the 2nd question what change in temp will i use?
So I found that you would have to set it up using (4.1)(3.1)/(2.9)(x-1.1). The x includes the .5 of NO2 already added, so to find how much was added to the original, find x and just subtract .5. The "x" value was the new initial value used to raise SO3 to
i thought you would have to decrease x from SO2?
The answer is only temperature changes. The equilibrium constant becomes larger with a temperature change, the forward reaction is favored and the eq. shifts to the right. If the constant becomes smaller, the reverse reaction is favored and shifts to the
I tried to answer the hwk using this tip for part B, but I didn't get it right...is there another way to set it up?
for this one, when we set up the ice chart, and we have the M of HI, and we have to subtract x, would we subtract 2x because the mols of HI is two?
I also just found this site. DrBob222 is great!
actually, the right answer was 35.8 KJ
I got 896.3 KJ. Does this seem right?
but I don't have the K or the Ea. Do you mind posting a sample?
