which reaction is an example of heterogeneous catalysis?\nethene gas reacts with hydrogen gas by using a nickel catalyst.\nhydrogen peroxide decomposes by using an aqueous iodide ion catalyst.\nformic acid decomposes by using an acidic catalyst.\nsulfur dioxide gas is converted to sulfur trioxide gas by using nitrogen chloride gas.
Answer
Brief Explanations:
Heterogeneous catalysis involves a catalyst in a different phase from the reactants. In the reaction of ethene gas with hydrogen gas using a nickel catalyst, the nickel is a solid while the reactants are gases. In the other options, the catalyst and reactants are in the same phase (aqueous - aqueous or gas - gas).
Answer:
Ethene gas reacts with hydrogen gas by using a nickel catalyst.
