Explanation / Answer

this is ahrrenius law so

ln(P1) = ln(3.43) = 1.2325

ln(p2) = ln(8.87) = 2.182

1/T1 = 1/275 = 0.003636

1/T2 = 1/875 = 0.00114

rise = y2-y1 = 2.182-1.2325 = 0.9495

run = x2-x1 = 0.00114-0.003636 = -0.002496

slope = rise/(run) = 0.9495/-0.002496 = -380.408

H/R= -slope

H = R*--380.408 = 8.314*380.408 = 3162.7121J/mol
