It is quite easy and a basic level reaction of acids and metals. Where metal salt is formed and hydrogen gas is evolved. I can see that you got your answer but as you are one of the few who requested for an answer. I wont let it go.
H2SO4 + Zn → ZnSO4 + H2….
The reaction is catalysed by copper. The rate of reaction can be compared by means of the rate of production of hydrogen gas bubbles.
thank you
