The half life for the first order conversion of cyclobutane toethylene, C 4 H 8

Question

The half life for the first order conversion of cyclobutane toethylene, C4H8(g) --->2C2H4(g) is 22.7 s at a particular temperature. How manyseconds are needed for the partial pressure of cyclobutane todecrease from 100 mmHg to 10 mmHg? PleaseEXPLAIN.

Explanation / Answer

first find k k = ln2/t = ln2/22.7 = 0.0305 use this equation to solve ln[P]t = -kt + ln[P]o ln[10] = -0.0305t + ln[100] t= 75.5seconds hope that helps ln[10] = -0.0305t + ln[100] t= 75.5seconds hope that helps
