Please explain the answers

a) What is meant by "conversion , indicated along the y-axis of diagrams (a) and (b) ? Give a simple mathematical equation for the calculation of a. (3 P) b) Diagram (a) shows isothermic curing at different temperature levels. Please explain - why with increasing temperature level the conversion rises faster immediately after the start of the curing reaction. (3 P) why the conversion curves at constant temperature levels do not increase in a linear way, but flatten over time and run out at different levels of . (3P) c) Diagram (b) shows curing at different constant heating rates. Please explain - why, for any of the shown heating rates, conversion 1.0 is achieved. (3 P) why all curves have s-shape, which at lower heating rates is more pronounced. (3 P) d) Bonus task: Cured thermosets with conversion levels far below 1.0 often cause problems during application. What could be reasons for that ? (3 extra points)
