Following reaction occurring in an automobile `2C_(8)H_(18)(g)+25O_(2)(g) to 16CO_(2)(g)+18H_(2)O(g)`. The sign of `triangleH, triangleS and triangleG` would be-

Options

A. `+, -, +`
B. `- ,+, -`
C. `- ,+, +`
D. `+, +,-`

Answer

B

Explanation

For Combustion reaction, `Delta H` is negative, `Delta n_(g)= (16+18) - (25+2)= +7`, so `Delta S` is +ve, reaction is spontaneous, hence `Delta G` is -ve.
