A graph of experimental data is a straight line when ln[H2] is plotted versus time. Which rate law fits the data?

Question

1 Rate = k(ln[H2])
2 Rate = k/[H2]
3 Rate = k[H2]
4 Rate = k[H2]2

Answer 1

straight lines have a constant slope. That is often written

y = kx

In this case, the quantities have different names, but it should be clear which choice is correct if you just use your names instead.
