I have to use this equation to get the answer (t)=time. V=S+a*t I divided t by both sides, but get a little confuse do I divide V by both sides as while is the answer: t = V/s+a/S??

How can you calculate activation energy in (kj/mol)? When all that is given is inverse temperature, and natural log reaction constant? Inverse: 1/278 for Kelvin temp, 1/308 Natural Log Reaction Rate Constant: 4.3 5.5
Chemistry
How do you do the inverse of absolute temperature? My kelvin temperatures are: 298 308 318 328 338 348 358 368 378 Taking the natural log of both sides of both sides of the equation gives ln(k) = ln(A) – E/RT. Thus, a graph of the natural log of the reaction rate constant...
Calculus
I'm having problems with this one. Can't get the right answer. Differentiate the following using the chain rule. f(x) = squareroot(x^2+1)/(3x+1) I know that I can take the whole thing and put it to the (1/2) and differentiate that then use the quotient rule to differen...
