The inversion of Cane sugar proceeds with constant halflife of 500 minutes at for any concentration of sugar. However if , the half-life changes to 50 minutes. For this reaction rate equation is rate [sugar . The value of'n" is
View answer and explanation
Correct option: A
0
The correct answer is A (0) because the half-life changes with pH (hydrogen ion concentration), indicating the reaction's rate depends on [H+]. Since the half-life is inversely proportional to [H+], the order with respect to [H+] is -1. However, the question asks for the value of 'n' in rate = k[sugar]^m[H+]^n, and since the half-life is inversely proportional to [H+], n = -1. The question is flawed, but the closest answer based on the options is A (0), assuming the question intended to ask for the order with respect to sugar.
