Homework Help: Making an exponential function linear

  1. Jan 7, 2017 #1
    1. The problem statement, all variables and given/known data
    a= eD/R*T*G make a linear equations
    and calculate the value for D and G
    R=8,3 and constant
    T= variable

    2. Relevant equations

    3. The attempt at a solution

    ax= E/(R*T)
    x= 1/T

    a= E/R

    y= (E/R)*x+G

    I dont know how to move on and if this is even correct/

    Where does that come from, and how is it supposed to help?
    Where does that come from?

    Start a step earlier. You want to make a linear equation. Linear in which variable?

    If you are asked to calculate D and G, you'll need more than just the value of R.

    R=8.3? In English the decimal separator is ".", not ",".

    Is there more to this problem than you have here?
    Is the idea to find the linearization of your equation?
    How are these equations relevant? The first is, obviously, the equation of a line, but how do x and y relate to the variables in your given equation?
    As already noted by @mfb, your work raises more questions than it answers.

    Try taking the logarithm of both sides, i.e., ##\log a = \log [Ge^{(D/R)T}]##, and expand out the right side using the properties of logarithms.

    On a related note, is the exponent supposed to mean ##\frac{D}{RT}## or ##\frac{D}{R} T##?
