52. Reactions with high activation energy are
53. The minimum energy required to allow a chemical reaction to proceed is termed as the 'threshold energy '. Chemical reaction with low activation energy are
54. In a semi-batch reactor,
55. Catalytic action in a catalytic chemical reaction follows from the ability of catalyst to change the
