Hello, we are supposed to write a lab about how the concentration of a substrate affects the amount of gas produced. My teacher wants a graph with concentration of substrate in the x-axis, and rate of reaction in the y-axis. The problem is that we have only measured the volume of the gas at two times: when t=0, and when t=120 s, and this was according to her instructions. We were only supposed to measure the volume at these two times. How do we find the rate of reaction from this?
Does anyone use their degree?
