For the isomerization of n-butane to isobutene we have G= -RT LnK where R= 1.9872 and K= (isobutene)/(n-butane) The temperature dependent Gibbs free energy (in calories) for isobutene and nbutane are given by G= -31450 - 70.42 T and G= -29810- 74.10T respectively a) find K as a function of T b) find the max temperature for which K is greater than or equal to 1 c) does it seem preferable to carry out the reaction at a low temp?
An infinitely long line of charge has a linear charge density of 5.00×10^?12 C/m. A proton is at distance 12.0 cm from the line and is moving directly toward the line with speed 1500 m/s. How close does the proton get to the line of charge?
