The correct answer with a full explanation. Practice this interactively instead →
रासायनिक अभिक्रियेचा वेग हा साधारणपणे _____ Chemical reaction rates generally _____
1)वेळेनुसार संपूर्णपणे स्थिर राहतो / are constant throughout a reaction
2)सुरुवातीला कमी असतो आणि वेळेसह वाढत जातो / are slow at the beginning and increase with time
3)सुरुवातीला जास्त असतो आणि वेळेसह कमी होत जातो / are greater at the beginning of a reaction and decrease with time✓ Correct
4)असे सर्वसाधारण विधान केले जाऊ शकत नाही / no such generalization can be made
The rate of a chemical reaction is highest at the beginning because reactant concentrations are at their maximum, and it decreases over time as reactants are consumed.
