Real questions that test this
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.
जस जशी रासायनिक अभिक्रिया होत रहाते वेळेनुसार तिचा वेग _________ With the progress of any chemical reaction, the rate of the chemical reaction _________ with time.
1)decreases✓ Correct
2)increases
3)remains constant
4)increases very fast
The rate of a chemical reaction generally decreases with time as the concentration of reactants decreases and gets converted into products.
