A decomposition reaction in the first order has a rate constant of 1.26 x 10-4/sec. If the initial concentration of the reactant is 0.644 M. how much time will it take before 20% of the reactant has decomposed? 28a) In blank #1, type-in the working formula to solve for the time required. Enter the algebraic formula as a one-line equation and without spaces in between characters. Use lowercase for all fonts. 28b) In blank #2, type in your answer for the time it will take for 20% f the reactant to decompose. The answer is in seconds but do not include the unit. Enter your answer as a whole number with four significant figures.

Transcribed Image Text:(#28) Reaction Rates and time.
A decomposition reaction in the first order has a rate constant of 1.26 x 10-4/sec. If the initial
concentration of the reactant is 0.644 M. how much time will it take before 20% of the reactant has
decomposed?
28a) In blank #1, type-in the working formula to solve for the time required. Enter the algebraic
formula as a one-line equation and without spaces in between characters. Use lowercase for all fonts.
28b) In blank #2, type in your answer for the time it will take for 20% f the reactant to decompose.
The answer is in seconds but do not include the unit. Enter your answer as a whole number with four
significant figures.
