It will take 444 seconds for 5g of this reactant take to reduce to 3g
Explanation:
Expression for rate law for first order kinetics is given by:
where,
k = rate constant =
t = time for decomposition
a = initial amount of the reactant = 5 g
a - x = amount left after decay process = 3 g
Putting in the values we get:
