Answer to Question #119535 in General Chemistry for Brady

Question

I start with 100g of product for reaction 1, and it proceeds at a rate of 23g/min. I start with 40g of product for reaction 2, and it proceeds at a rate of 49g/min. At what point will they have the same amount of product?

Answer 1

see for reaction 1 rate is 23g/min

and for reaction 2 rate is 49g/min and amount of product is 40 grams

so time required only is

(60 seconds*40grams /49 grams) that is almost 49 seconds

since for same amount like 40 grams for reaction 1

time required is (60sec*40grams/23grams)

that is equal to 104.37 seconds

so after 104.37 seconds both will be having same amount of product
