Hello , could you please solve this question , as the answer I am getting is different from the one in the marking scheme, I am getting 2.8x10^-3 but in the marking scheme it is 2.8x10^3

Thanks in advance

In a further experiment, the rate constant, k, for the decomposition of hydrogen peroxide catalysed by the enzyme catalase was determined at a range of temperatures, T. A graph of Ink against 1000 x 1/T was plotted. 7.3 7.1 6.9 6.7 6.5 Ink 6.3 6.1 5.9 5.7 5.5 3.1 3.15 3.2 3.25 3.3 3.35 3.4 3.45 3.5 3.55 3.6 1000 x 1/T (K"') (1) Determine the gradient of the graph.
