Video transcript

Hello, everyone in this video, We're trying to see if this following statement is true or false. The statement reads the reaction of N two gas and C. 02 gas occurs spontaneously to produce gas, and so gas at room temperature and standard pressure conditions of one atmosphere. So let's see here, we know that our N to N C. 02 are always intact and normal standard atmospheric conditions, but the products that they're talking about, which is N. O. Gas and so gas will not form spontaneously without any sort of intervention. Therefore, the statement then is false. So the false is going to be my final answer for this. Thank you all so much for watching.

Textbook Question

Indicate whether each statement is true or false. (a) A reaction that is spontaneous in one direction will be nonspontaneous in the reverse direction under the same reaction conditions. (b) All spontaneous processes are fast. (c) Most spontaneous processes are reversible. (d) An isothermal process is one in which the system loses no heat. (e) The maximum amount of work can be accomplished by an irreversible process rather than a reversible one.
