zero oder reaction is the one whose rate is independent of concentration rite??
now a order of a reaction can be negative rite?
so now here is a reaction
A+B----->C
now if if the rate law is
rate=k[A]^-1.[B]^1
now order of the reaction is 0.
but if i change conc of a the rate will also change rite.
then how a can it b a o order reaction.
plz clear my doubt

I got hired to teach high school physics but I picked up a chemistry class. I can handle most of it but I'm rusty. I was showing the structure of some molecules like benzene ring, water, etc. One of my students asked me how do we know what the shape of these things are if they are so small and I honestly couldn't answer. Can someone explain to me (so I can explain it to smart high school students) how we know what the structure of molecules looks like when they're so small. Thank you.

Aluminum hydroxide reacts with sulfuric acid as follows:
2Al(OH)3 + 3H2SO4--> Al2(SO4)3+6H2O
Which is the limiting reactant when .500 mol Al(OH)3 and .500 mol H2SO4 are allowed to react?
How many moles of Al2(SO4)3 can form under these conditions?
How many moles of the excess reactant remain after the reaction?

equation:

H2(g) + CO2(g) <===> H2O(g) + CO(g)

question:

Kc = 5.84 at 1510K. If each of the four species was initially present at a concentration of 6.000M, calculate the equilibrium concentration of the CO(g) at this temperature.

answer could be...

2.488
9.761
9.337
8.488
3.512

These papers should also detail the experimental setup used to formulate the isotherms....

Other important similar papers on Sips, Redlich-Peterson and Toth isotherms are desirable as well....
