Rate Law / Rate Constant? 10 Points!!?*
Q. How do I find the rate law and the rate constant of something??It goes something like this:2Fe^2+ + Cl2 ------> 2Fe^3+ + 2ClH+ (catalyst)>>>>>>Fe2+ Cl2 H+ RateExp1..0020 .0020 1.0 1.0x10^-5Exp2:.0040 .0020 1.0 2.0x10^-5Exp3..0020 .0040 1.0 2.0x10^-5Exp4..0020 .0020 .05 2.0x10^-5Exp5..0040 .0040 1.0 4.0x10^-5Exp6..0020 .0020 .01 1.0x10^-4And it asks to find reaction order with Fe, Cl and H+, and also the rate law and relative rate constant...thanks!!

A. if we write the rate law of the reactionrate = k([Fe2+]^(a))([Cl2]^b)([H +]^c) (equation 1)where rate = rate of reaction (given)k = rate constant (to be determined)[Fe2+] =concentration of Fe2+[Cl2] = concentration of Fe2+[H+] = concentration of acid catalysta= rate order of Feb= rate order of Cl2c = rate order of H+determine the rate orders first by taking two experiments wherein only one reactant is changing and the others are constant. Write their rate laws for example Exp1 rate law :(1.0x10-5 = k([0.0020]^a)([0.0020]^b) ([1.0]^c)Exp2 rate law (2.0x10^-5 = k([0.0040]^a)([0.0020]^b) ([1.0]^c)(exp1 rate law)/(exp2 rate law) will give you(1.0x10^-5/2.0x10^-5)= (0.0020/0.0040)^a (equation 2)the k, [Cl2]^b and…

Mortgage interest rate, going up?*
Q. Interest rate on 30% fixed is now 6,25$% or over 6 %.In last few weeks, it was below 6%. It was like 5.75%.Will the interest rate keep going up and be back t normal?My broker is saying I shuld put an offer and lock in a rate.He further says inflation is in danger and as a result of that, interest rate will go up and up. Will the interest be more then what it was may months ago?I plan to move out of apartment in the end of May 08 to a possible new house, Should I lock in rate now?can I lock in rate now but move out in May? Is there financial disadvanage in doing that?What locking in rate really means?IN GFE, it has this, Compensation paid to broker $ 3,633.00 YSP PAID TO BROKER 1.5,. Is this something I have to pay out of… [cont.*]

A. MORTGAGE RATES ARE GOING UP AND WILL NOT BE GOING DOWN ANY TIME SOON!A good broker can submit your loan and lock an interest rate before you even pick out a house if you are looking to buy in 60 - 90 days.The interest rates won't go up like crazy, but anything under 6% is pretty much unheard of anymore. Last month I was able to get 5.5% and lower rates, now it's impossible.90 days is the longest rate lock you can do.Locking a rate means you "lock" in that day's interest rate that the mortgage company offerred that day. Every day mortgage companies change their interest rates either increaseing or decreaseing. By locking a rate you are guaranteed that rate for a set period of days *30, 60, or 90 days* wether rates go up or down.…

Inflation RATE question?*
Q. "Does inflation necessarily hurt everone?" The interest rate you pay for a loan has two parts: one rate compensates for the expected rate of inflation and one part that is the real interest rate, over and above the rate of inflation. If the bank makes a mistake and inflation is higher than they expected, what happens to the REAL rate of interest?

A. Yes inflation does hurt everyone in one way or another. Even expected inflation creates costs, in particular menu costs and shoe-leather costs. Menu costs are the costs of changing prices, (such as a restaurant reprinting their menus, hence the name). Shoe-leather costs are the costs incurred in the process of economising on holdings of cash (people trying to minimise their holdings of cash), such as having to make more trips to the bank because of higher inflation meaning higher prices.Despite these costs, inflation is needed to help stimulate growth in an economy and in some economies, keep unemployment down.If the bank makes a mistake and inflation is higher than they expected, the real interest rate will decrease, so, in real terms,
