A second-order reaction was observed. The reaction rate constant at 25 oC was found to be 6.50 x 10-3L/mol and at 70 oC it was found to be 2.30 x 10-2 L/mol. Calculate the activation energy of this reaction.

The difference between a red shift and a blue shift has to do with wavelength frequency. t or f

Use the right-hand rule for magnetic force to determine the charge on the moving particle. this is a charge.

Check the following equation for dimensional homogeneity: ⅆ mv=∫t1t2(f⁢cosθ)ⅆt where m is mass, v is velocity, f is force, θ is an angle, and t is time. check that each term in the equation has the following dimensions: [malbec] where you are to choose the coefficients a, b, c.
