HiI simply can’t wrap my head around this problem.I’m to calculate the rate constant and reaction order of ‘A + B -> products’Where -d[A]/dt = k[A]^x*[B] and -d[A]/dt = kobs*[B] and ‘A in vast excess with respect to B’ (whatever that means, is it [A] >>> [B] or opposite?)I only have a table of [A] and kobsI think I’m to combine the two equations, but I don’t really know what to do.Problem text is uploaded as a picture.
