WebUsing an Arrhenius plot: A graph of ln k against 1/ T can be plotted, and then used to calculate Ea. This gives a line which follows the form y = mx + c. The graph of ln k against 1/T is a straight line with gradient -Ea/R. From the graph, the equation in the form of y = mx + c is as follows: WebThis Data Booklet is provided with AQA A-level Chemistry question papers. 1.0: H: hydrogen: 1 4.0: He: helium: 2 10.8: B: boron: 5 12.0: C: carbon: 6 14.0: N: nitrogen: 7 …
WebStep 1: Convert the entropy value in kilojoules. Δ Sꝋ = +344 J K -1 mol -1 ÷ 1000 = +0.344 kJ K -1 mol -1. Step 2: Substitute the terms into the Gibbs Equation. Δ Gꝋ = Δ Hreactionꝋ - TΔ Ssystemꝋ. = +135 - (298 x 0.344) = +32.49 kJ mol-1. The temperature is 298 K since standard values are quoted in the question.
