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: http://www.a-levelchemistry.co.uk/uploads/9/0/4/5/90457821/aqa-7405-sdb_2.pdf
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.

C13 NMR 2. H (proton) NMR There is only around 1% C13 in organic molecules but modern NMR machines are sensitive enough to give a full spectra for C13 The C13 spectra is a simpler spectrum than the H NMR Equivalent Carbon atoms. diamond math gameWebA Level Chemistry A 5 OCR 2024 A LEVEL CHEMISTRY A H432 Most candidates need more practice at writing systematic names using oxidation numbers.
