Q

for an order 1 reaction explain why doubling the temperature increases the rate alot greater than doubling concentration of a reactant

A

reaction occurs when particles have energy equal or greater than activation energy

doubling temperature gives many more molecules energy greater than or equal to activation energy

where as doubling only doubles the molecules with energy greater than or equal to activation energy
