Q. The effect of a catalyst on a chemical reaction is to:

रासायनिक प्रतिक्रिया पर उत्प्रेरक का प्रभाव होता है:

A
Change the equilibrium constant
संतुलन स्थिरांक बदलें
B
Provide an alternative pathway with lower activation energy
कम सक्रियण ऊर्जा के साथ एक वैकल्पिक मार्ग प्रदान करें
C
Increase the energy of the reactant molecules
अभिकारक अणुओं की ऊर्जा बढ़ाएँ
D
Change the heat of reaction
प्रतिक्रिया की गर्मी बदलें

Explanation

A catalyst lowers the activation energy by providing an alternative path, thus increasing the reaction rate without changing equilibrium constants or the heat of reaction.
