यदि अम्ल की सांद्रता बदलकर धातु के साथ अभिक्रिया की गति मापी जाए तो स्वतंत्र चर क्या है?
If acid concentration is changed and the reaction rate with a metal is measured, what is the independent variable?
Explanation opens after your attempt
A. अम्ल की सांद्रताAcid concentration
Concept
Acid concentration is deliberately changed, so it is the independent variable. Reaction rate is the dependent variable.
Why this answer is correct
The correct answer is A. अम्ल की सांद्रता / Acid concentration. Acid concentration is deliberately changed, so it is the independent variable. Reaction rate is the dependent variable.
Exam Tip
अम्ल की सांद्रता जानबूझकर बदली जाती है इसलिए यह स्वतंत्र चर है। अभिक्रिया की गति आश्रित चर है।
