If, at t=30 sec,[A]=100 moles/L\mathrm{t}=30 \mathrm{~sec},[\mathrm{A}]=100 \mathrm{~moles} / \mathrm{L},

at t=40 sec,[A]=80 moles/L\mathrm{t}=40 \mathrm{~sec},[\mathrm{A}]=80 \mathrm{~moles} / \mathrm{L},

at t=50 sec,[A]=64 moles/L\mathrm{t}=50 \mathrm{~sec},[\mathrm{A}]=64 \mathrm{~moles} / \mathrm{L}

For a reaction, A→BA \rightarrow B, the order will be
View answer and explanation
Correct option: A
1
The correct answer is A (1) because the concentration decreases by a constant factor over equal time intervals, indicating first-order kinetics.
