A reaction is 50% complete in 34.0 min.

1.) How long after its start will the reaction be 75% complete if it is first order?

2.)How long after its start will the reaction be 75% complete if it is zero order?

steps would be helpful

  • chemistry - ,

    For 1 use ln(No/N) = kt
    Use the 34 min and 50% complete to determine k, then use that k and the same equation to use the conditions in problem 1.

  • chemistry - ,

    So its Ln ( 50/100) = k (34 min)?

  • chemistry - ,

    for the second part do i subtract 100-75 = 25 = -(the constant)(time)
