I thought the volume was given so that the concentration can calculated an utilized in the rate expression. Am I not supposed to calculate the concentration based on the mols being consumed? :confused:

From the balanced equation, a 2: 1 mol ratio is noted between NO and Cl2 So if one mol of Cl2 is used up then 2 mols NO would be used up [NO] = 1M [Cl2] = 0.5M Rate= (0.000384) (1)2 (0.5) = 0.000192moldm-3s-1

So does that mean that since half the Cl2 (0.5mols) is used then half the NO is used (2.5mols)? [NO] 2.5mols in 2dm3 2.5mols in 2L ∴ 1L = 1.25mols [NO] = 1.25M Rate = (0.000384) (1.25)2 (0.5) = 0.0003moldm-3sec-1

Homework Statement The Reaction; 2NO(g) + Cl2 (g) → 2NOCl (g) Is second order in NO and first order in Cl2. Five moles of nitric oxide and two moles of Cl2 were brought together in a volume of 2dm3 and initial rate was 2.4x10-3 moldm-3sec-1. What will be the rate when one half of the...

Is it feasible to form a S+ cation? Goin on the basis that the electronic configuration is 1s2,2s2,2p6,3s2,3p4 the valence electrons would be 3s2 and 3p4. So I'm thinking that it would be relatively easy to remove the 4th electron in the p subshell BUT looking at the 6 valence...

that really cleared things up...thank you.

i'm having trouble distinguishing between magnetic flux and magnetic flux density...can someone please explain to me? also why is it sometimes used interchangeably?

Thank you very much. The link was also very helpful.

Aerobic respiration of say seedlings with an intact cotyledon: what happens between the energy produced in the reaction C6H12O6 + 6O2 => 6CO2 + 6H2) + ATP and the ATP releasing energy to drive biochemical activities? Is energy produced and then converted to the ATP? Or is the...

Can someone explain the role of eddy currents that produce levitation such as in the floating tube expt or the jumping ring? How is the jumping ring altered to achieve stability? i.e raising the ring a fixed distance above the coil? Like in maglev transportation...or is it just dependant on the...

when an electron collides with another, say a hydrogen electron, when the hydrogen electron is promoted, what happens to the incident electron?

when a current in a coil induces a current in another that is in series with it. Would the direction of the induced current change if the current falls? With Lenz's law the induced current would oppose the current of the first coil but what would happen to the induced current if the switch...

ohh, i did miss that. Thanks very much

Homework Statement A particle of mass 3x 10^-12kg carrying a charge of +4.0x 10^-14C is released at the upper plate of a pair of horizontal parallel conducting plates placed in a vacuum. Homework Equations (1) Calculate the net force on the particle: I added the electric force VQ/d and...
