(1 point) Two chemicals A and B are combined to form a chemical C. The rate of the reaction is proportional to the product of the instantaneous amounts of A and B not converted to chemical C. Initially there are 63 grams of A and 100 grams of B, and for each gram of B, 2 grams of A is used. It has been observed that 40.75 grams of C is formed in 10 minutes. How much is formed in...

Two chemicals A and B are combined to form a chemical C. The rate, or velocity, of the reaction is proportional to the product of the instantaneous amounts of A and B not converted to chemical C. Initially, there are 100 grams of A and 50 grams of B, and for each gram of B, 2 grams of A is used. It is observed that 25 grams of C is formed in 5 minutes. How much is formed in 20...

1. Chemical reaction rates are proportional to a rate constant, k, which changes with temperature according to the equation : For a certain reaction: Q = 8000 cal/mole R = 1987cal/mole K k0 = 1200 min-1 k = k0·e–Q/(R·T) Find the values of k for temperatures from 100K to 500K in 50-degree increments. Create a table for your results. The table should contain two columns, with left column containing the temperatures and the right column containing the correcsponding values of...

Objective Find the ratio of moles of reactant to moles of a product for the reaction below. Compare mass and mole amounts of reactants to determine the amount of products that can be/are made. Background Chemical reactions are represented by balanced chemical equations. Proper interpretation of an equation provides a great deal of information about the reaction it represents and about the substances involved in the reaction. For example, the coefficients in a balanced equation indicate the number of moles...
