Catalase is an enzyme present in potato tissue. It speeds up the decomposition of hydrogen peroxide into water and oxygen. Five identical potato discs were placed into $15\text{ cm}^3$ of a $3\%$ hydrogen peroxide solution at a temperature of $20\degree\text{C}$. The time needed to produce $5\text{ cm}^3$ of oxygen was measured. The same method was then carried out at $30\degree\text{C}$, $40\degree\text{C}$, $50\degree\text{C}$, $60\degree\text{C}$ and $70\degree\text{C}$. Which graph would represent the findings of the investigation?
