Chemical Kinetics, finding rate of reaction

AI Thread Summary
To calculate the rate of reaction for the production of carbon monoxide gas from formic acid, the volume of gas produced (44.6 mL) must be converted to moles using the ideal gas law. The rate of reaction can be expressed in terms of the change in moles over time (dn/dt) rather than concentration (dC/dT). Participants in the discussion emphasize the need to find the molar volume at the given conditions to complete the calculation. The focus is on understanding how to relate the volume of gas produced to the rate of reaction. Proper conversion and application of the ideal gas equation are crucial for determining the reaction rate accurately.

Homework Statement



At 25 C a catalyzed solution of formic acid produces 44.6 ml of carbon monoxide gas in 30s.

a) Calculate the rate of reaction with respect to CO(g) production.

Homework Equations



Rate = dC / dT

The Attempt at a Solution



dC should be expressed in mol/L but I do not know how to find this with the given 44.6 mL

Any hints as to what I should be looking for>

Bump, anyone? Still stuck on this
 
Ideal gas equation? You won't be able to give the rate in terms of dC/dT, rather in terms of dn/dt, this is a valid way of describing the kinetics.

TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...
I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
