And so this would be the value for the first rate constant, 5.79 times 10 to the -5. And then T2 was 510, and so this would be our second rate constant here. So 1.45 times 10 to the -3. And so let's plug those values back into our equation. So it would be k2 over k1, so 1.45 times 10 to the -3 over 5.79 times 10 to the -5. mfs plumbing water and heater
