AI Thread Summary
To calculate the equilibrium constant (K) for the reaction between ethanol and acetic acid at 100°C, the initial concentrations of both reactants are 0.810 M, and the equilibrium concentration of acetic acid is 0.748 M. The change in concentration (x) can be determined by subtracting the equilibrium concentration from the initial concentration. The reaction follows pseudo first-order kinetics, and the equation kt = ln(a/(a-x)) can be applied, where t is the temperature in Kelvin (373 K), a is the initial concentration, and a-x is the equilibrium concentration. By substituting these values into the equation, K can be calculated for the reaction at the specified temperature.

I have this problem to solve and I am having dificulity it doing so:

An aqueous solution of ethanol and acetic acid, each with a concentration of 0.810 M is heated to 100 C. At equilibrium, the acetic acid concentration is 0.748 M. Calculate K at 100 C for the reaction.

C2H5OH (aq) + CH3COOH (aq) <=> CH3COOC2H5 (aq) + H2O (l)

This isn't for homework or anything like that. I am just going back through old college textbooks and came across this one.

Thank you for help in advance.

I think this reaction follows pseudo first order kinetics, so kt=ln\frac{a}{a-x}. You have t=373k, a=.810 a-x=0.748, solve for k.
 

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

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...
