Then how would "a" affect the volume of gas? I'm confused on that part?
I'm big dumb, r2 = 0.033/1.73 = 0.019 was the correct r2 value. what I did was wrong for r2, thus causing me to mess up to final answer.
Thanks again, I understand your explanation.
oops clicked submit by accident 2) I used an ICE table N2(g) + 3 H2(g) ⇔ 2 NH3(g) I : 1 mol 3 mol 0 C : -x -3x +2x E : 1-x mol 3-3xmol 2x mol since [H2]eq = 0.12 mol/L, then 3-3x = 0.12, therefore x = 0.96 to get [NH3]eq = 2 x 0.96 =
ok so, -1/4 [ΔNH3] / ΔT = positive, since - ( - 0.00264) x 1/4 ? (I turn mins to seconds and divided the M) .... ? Thanks for your first explanation.
Also if reactants are negative wouldn't that mean that my final answer for my average rate of both NH3 and O2 would be negative as well? example: -1(1/4*0.158 )?
What do you mean by "Remember the negative sign for reactants and positive sign for formation of products." how would this play out (would the outcome of the answer be negative, positive? I'm confused can you give an example and explain please)? Also, Why
I have a question about the rate law, I understand that it is based on the slow step, but I don't understand why is it rate = k [B2] instead of rate = k [A] [B2]? Also my teacher said that I needed to show my steps but I don't know how to since this
I have a question, isn't it suppose to be 0.150 L instead of the 0.100 L because " 100.00 mL sample of 0.355 mol/L HCl(aq) is mixed with 50.00 mL of excess NaOH(aq). " or is it just 0.100 L?
