Best answer

Answer: 1. [graph option 1, see figure]

Key idea: \(\ln k=\ln A-\dfrac{E_a}{R}\cdot\dfrac1T\), a straight line with negative slope \(-E_a/R\) and positive intercept \(\ln A\).

Only graph (1) falls with increasing \(1/T\) and cuts the \(\ln k\) axis at a positive value. Graphs 2, 3 and 4 have positive slopes. Option 1.
