I have tried every possible combination to come up with the cross diagram to no avail Your help is needed please😩😩😩

To be honest with you sir I haven’t an idea I was just doing some research now and I found out that the enthalpy of ideal gases strictly depends on temperature and that there will be no change in enthalpy for an isothermal reaction involving ideal gases Does this mean the answer is none of...

Yes Hess’s law states that the heat change in a chemical reaction is the same regardless of the number of stages taken to obtain the final product But how does it relate to this qeustion

I feel that the answer is B) because Increasing the pressure increases the intermolecular forces Of the gas molecules but I do not see how this In effect will lead to an increase in the enthalpy

Please how did you type the equation , i see it as( ##P_1V_1 = nRT_1##) but it actually appears in the message itself as the ideal gas equation ??

Ok ✅

Yh i agree that there seems to be a problem with the qeustion because i realized that if you change the 75mmhg to 750mmhg then the answer becomes D) 55.9cm3 I still want to know how i could go about with the problem using the ideal gas equation as you said Thanks anyway @Steve4Physics and...

I just did the necessary corrections and solved it solved it again but my answer still doesn't fall among the provided answers

I am confused it’s actually an mcq qeustion, here is the question

This is my working using the combined gas equation

I don't really understand how i can solve this question using the ideal gas eqaution, i just tried and it’s giving me an absurd value, would appreciate if you can do so , i want to see how you go about it

Note taken

Do i now proceed by substituting the said values in the combined gas equation (P1V1 / T1 = P2V2 / T2 ) then find the final volume?

I do not quite understand what you mean here sir

I meant 75mmhg and not 750atm sorry for the mixup😅
