    • Done four reactions at different temperatures
    • calcualted the inital rate of reaction at each temperature
    • substituted this into the rate equation to calcualte the rate constant
    • plotted a graph of 1/T against ln(rate constant)
    • Drawn a straight line of best fit and calculated the gradient
    • Put the gradient equal to -Ea/R
    • Converted Ea from J to KJ

    i think you meant you plotted ln(rate constant) against 1/T
    Arrhenius eqn is k = Aexp(-E/RT)
    so ln k = ln(A) - (E/R)(1/T)
    y = mx + c
