• Determine % H2O2 decomposed in first 500 s in a first order decomposition reaction of H2O2? k=7.30x10-4 s-1

Given rate constant of the first-order reaction is:

K=7.30x10^-4 s-1

Time t=500s

Determine % H2O2 decomposed in first 500 s in a first-order decomposition reaction of H2O2?

Explanation:

The expression for the rate constant of the first-order reaction is:

where,

k=rate constant

t=time period

ao=initial amount of the reactant

a-x=amount of a remained after time t.

Substitute the given values in the above formula to get ao/a-x value.

% of H2O2 decomposed is:

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
