initial rate

This method is used for reactions where more than one reactant species are involved. Initial rates of the reaction are determined by varying the concentration of only one reactant while keeping the concentrations of other reactants constant. Initial rate..

Choose the exponential function with the initial value 12, decreasing at a rate of 0.47% per week. => S( t ) = 47(0.0012) t or S( t ) = 12(0.0047) t or S( t ) = 12(0.9953) t or S( t ) = 47(0.0995) t..

The average annual rate of decrease in the population of a rare animal group is 4.5%. The initial population of the group is 2600. If the rate continues, estimate the population after 11 years. => 117 or 2483 or 1568 or 236..

Jim deposited some amount in a bank at a rate of 3% compound interest. What was the amount deposited initially, if the balance in his account at the end of 5 years is found to be $3000? => $2826.35 or $2485.45 or $2686.45 or $2586.20..

Suppose that the seal population in an island of Antarctica is 10,000 initially with a birth rate of (0.000002)P and death rate of (0.000001)P. What is the seal population after 60 years? [P = P(t) is the seal population after t years.] => 35,000 or 50,000 or 25,000 or..

A bacterial culture grows at a rate proportional to the number of bacteria present. If the size of the culture triples every one hour, then how long does it take for the culture to become 5 times the initial amount? => 2 hours or 146 minutes or 40.95 minutes or 88 minutes..

Kate started reading a story book. Initially, she read 20 pages. By the end of 4 days, she completed 84 pages. Find the average rate of reading the book and use it to determine the number of pages can be completed after 10 days. => 16 pages per day, 26 or 16 pages per day, 180 o..

Doctor Jerald started recording Joe's weight each month as a part of his treatment. His initial weight was 246 pounds. After two months his weight was found 236 pounds. Find the average rate of change in his weight and use it to determine his weight after the first 7 months. => ..

Example 6: A first order reaction is 40% complete in 50 minutes. What is the rate constant? In what time will the reaction be 80% comple..
