A chemical reaction begins with a certain amount of reactant. The graph shows the amount of reactant, in grams, remaining in a solution as a function of the time, , in minutes, since the reaction started. The graph is a line segment from to . What does the -intercept of the graph represent in this context?
The reaction consumes 10 grams of reactant per minute.
There were 100 grams of reactant in the solution when the reaction began.
After 5 minutes, 50 grams of reactant remained in the solution.
The reaction will stop after 10 minutes when all reactant is consumed.
